I realized today when I try to open calibre:

Re: python2 core dumped
I have the same problem:
[civ0@callisto tmp]$ calibre
Segmentation fault (core dumped)Here is the part of the strace where it gets weird. Its like I have no python2 - but its there and fine.
Here are the package versions of calibre and python2:
civ0@callisto ~> pacman -Q calibre
calibre 3.16.0-1
civ0@callisto ~> pacman -Q python2

Re: python2 core dumped
Does it work if you downgrade sip and/or pyqt5?

Re: python2 core dumped
I downgraded to the following package versions:
pacman -U python2-pyqt5-5.9.2-2-x86_64.pkg.tar.xz pyqt5-common-5.9.2-2-x86_64.pkg.tar.xz python-pyqt5-5.9.2-2-x86_64.pkg.tar.xzCalibre is now working again.
Thanks for the help.

Re: python2 core dumped
FWIW calibre works fine here with updated sip/pyqt5, as well as in a minimal chroot. So I'm not sure what the problem with your pyqt5 installation might be...
Did this actually work with the updated pyqt5 and the previous version of calibre??
Do you have any other software installed which uses pyqt5 and has the same issue?

Re: python2 core dumped
The only software I have installed using pyqt5 is git-cola from the AUR. I upgraded to
python2-pyqt5-5.10-1-x86_64.pkg.tar.xz
pyqt5-common-5.10-1-x86_64.pkg.tar.xz
python-pyqt5-5.10-1-x86_64.pkg.tar.xz and it still worked, but that that uses the python3 version. Calibre didn't work, which was expected.

Re: python2 core dumped
Absolute minimal python2 program to test python2-pyqt5
#!/usr/bin/python2
import sys
from PyQt5.QtWidgets import QApplication, QWidget
if __name__ == '__main__':
app = QApplication(sys.argv)
w = QWidget()
w.show()
sys.exit(app.exec_())Save that as a file chmod it executeable and it should spawn a window.

Did this actually work with the updated pyqt5 and the previous version of calibre??
Right after noticing the problem, I downgraded calibre to calibre-3.15.0-1, but it didn't help.

Re: python2 core dumped
Have you tried to create a new user and launch calibre there? This might help discard the possibility that it is something borked with your current calibre configuration.

Re: python2 core dumped
I am affected by this problem as well. I have spent an entire afternoon trying to figure out the reason for it but so far to no avail. But at least I can provide a very simple test case that happens to be used in the 'calibre' source code in many, many places:
23:~
% python3 -c 'import PyQt5.Qt'
24:~
% python2 -c 'import PyQt5.Qt'
zsh: segmentation fault (core dumped) python2 -c 'import PyQt5.Qt'The stack trace I get looks very much like the one that has been posted in the opening post of this thread. AFAIU the 'PyQt5.Qt' is a special module that imports all other 'PyQt5.*' submodules automatically so that you don't have to figure yourself which particular submodule you have to import when you want to access a certain Qt5 symbol.
For the record:
28:~
% pacman -Qs pyqt5 | grep local
local/pyqt5-common 5.10-1
local/python-pyqt5 5.10-1
local/python2-pyqt5 5.10-1
29:~
% pacman -Qs sip | grep local
local/python-sip 4.19.7-1

Re: python2 core dumped
We can't get any further without an actual backtrace. Unfortunately The-compiler still hasn't updated his debug packages to 5.10, so someone affected will need to compile sip and pyqt with debug symbols.

I have recompiled 'sip' and 'PyQt5' with debugging symbols to get a more expressive backtrace:

(gdb) I hope this is helpful.
EDIT: I just noticed that this backtrace pobably isn't helpful, because the function names are missing in sip.so. Looking into that now.
UPDATE: I now have a complete backtrace. The makefile generated by configure.py strips sip.so.

Re: python2 core dumped
Looks like QtNetworkAuth is somehow involved. I'd say bring this upstream to the PyQt developers with the full backtrace.

I think we're heading for the right direction. If I delete the file
/usr/lib/python2.7/site-packages/PyQt5/QtNetworkAuth.sofrom my system the crashes go away and I can build and run 'calibre' successfully. Very strange indeed ...

I just rebuilt 'python2-pyqt5' with the 'QtNetworkAuth' module disabled and indeed there are no more crashes on my system. If you want to try it for yourself you have to modify the PKGBUILD file for 'pyqt5' like this and then rebuild the complete package:
cd "$srcdir"/PyQt5_gpl-$pkgver-py2
python2 configure.py \
--confirm-license \
--no-sip-files \
--qsci-api \
--disable QtNetworkAuth \
-q /usr/bin/qmake-qt5The change is the addition of the second to last line; it is only needed for the 'python2-pyqt5' package, 'python-pyqt5' is not affected from what I can tell. Please note that this is just a crude band-aid, it does not solve the problem properly, but it works for me (at least).
I'd say bring this upstream to the PyQt developers with the full backtrace.
Maybe I will find some time this weekend to prepare a proper bug report. If anyone else wants to get ahead of me, don't hesitate!

Re: python2 core dumped
Don't forget, though, this issue doesn't seem to affect everyone. civ0 originally brought this up on IRC and we had 4 people there testing (me included) who couldn't reproduce the crash.

Yes, the fact that not everyone is able to reproduce the problem has kept me puzzled so I have scrutinized the 'strace' output again and I have found something interesting, but I need your help to verify my guess. So
can those of you who cannot reproduce the bug please check whether they happen to have the 'python2-enum34' package installed?
can those of you, who can reproduce the bug please check if they have not installed the 'python2-enum34' package? Does the crash go away when you install it?
Important addendum: If you conduct this test make sure that you have the 'qt5-networkauth' package installed as well, because if it isn't then 'PyQt5' won't even bother with it (because it can't load the necessary shared library) and you won't see any crash at all no matter whether you have 'python2-enum34' installed or not. Chances are you don't have 'qt5-networkauth' installed because until now it is not required by any package as a mandatory run-time dependency ('pyqt5' requires it only as a build-time and optional run-time depedendency). End of important addendum.
If your reports confirm my guess then the problem is caused by a missing run-time dependency:
% pacaur -Qi python2-enum34 qt5-networkauth
error: package 'python2-enum34' was not found
error: package 'qt5-networkauth' was not found
% calibre --version
calibre (calibre 3.16)
% pacaur -S qt5-networkauth
[...]
extra/qt5-networkauth 5.10.0-2
[...]

% calibre --version
zsh: segmentation fault (core dumped) calibre --version

[...]
community/python2-enum34 1.1.6-1

% calibre --version
calibre (calibre 3.16)By the way: I was able to reproduce the crash on my ArchLinux32 system as well and I was able to prevent it by installing 'python2-enum34'.

No python2-enum34 and no crash.

Re: python2 core dumped
For me calibre also crashed, after installing python2-enum34 it runs without problems.
