rapid photo downloader segmentation fault

Long time ago I installed rapid photo downloader from the Arch Linux repositories. It was working fine, but now it gives me segmentation fault when executing it.

$rapid-photo-downloader -v
INFO: Rapid Photo Downloader is starting
Fatal Python error: Segmentation fault

No info in the logs. Last time I could open the program was on the 3rd of July. 

Any idea about how could I diagnose/fix this problem?

Re: rapid photo downloader segmentation fault

Did you do a full system update?

If so, please create a new virgin user and start rapid-photo-downloader as this user. Does it also segfault?

Re: rapid photo downloader segmentation fault

Thank you for your answer. I have just created a new user and started rapid-photo-downloader from it, and I am afraid I still get a segfault...

EDIT: Also, my system is completely up to date.

Re: rapid photo downloader segmentation fault

I'd say, file a bug report. For me, the program does not immediatly segfault, but sometimes it gets stalled, depending on the filemanager it detects.

I have the same problem.

I think it might have something to do with this earlier bug, but i'm not sure.
I'll file a bug report.

Thanks.

Re: rapid photo downloader segmentation fault

I've had this problem for weeks now, was too busy to get my back up, though.

edit: All I wanted to say is: You're not alone.

Re: rapid photo downloader segmentation fault

So how do we go on from here with the pyqt5 issue that's Arch-specific? It's kinda annoying to have that nice piece of software not working for so long.

Re: rapid photo downloader segmentation fault

If it is really Arch specific, someone needs to file a bug report in Arch's bug tracker.

Re: rapid photo downloader segmentation fault

I reported the bug (please let me know if this is the right way, as it is the first bug I report in Arch Linux bug tracker) https://bugs.archlinux.org/task/67582

Any idea about how to circumvent the problem int he meantime? I made:

python -m pip install --user PyQt5==5.14.2
python -m pip install --user PyQt5-sip==12.7.2

and made .local/bin part of PATH but still I was unable to make rapid-photo-downloader work

Re: rapid photo downloader segmentation fault

Okay, got it to run with nasty hack-around. No liability granted! Might eat your cat!

sudo pacman -Rc pyqt5
pip install pyqt5
sudo pacman -S rapid-photo-downloader

1st of all: I have no idea, why it works now and didn't before.
2nd: Check the packages you uninstall when uninstalling pyqt5, it's nasty having to uninstall it along with every package depending on it.
3rd: I guess pip installs that stuff in some nasty user/home directory, rather then system-wide? No idea.
4rd: Then pyqt5 is re-installed again the Arch-ish way. Does it override the pip installation? No idea.
5ft: Afterwards it starts up without segfaulting...but...why?

Don't force uninstall pyqt5 using pacman, pip has an option for this:
pip install --force-reinstall PyQt5

3rd: I guess pip installs that stuff in some nasty user/home directory, rather then system-wide? No idea.

Yes, it does.

4rd: Then pyqt5 is re-installed again the Arch-ish way. Does it override the pip installation? No idea.

No, it doesn't.

5ft: Afterwards it starts up without segfaulting...but...why?

Apparently due to some difference in the PyQt5 wheel with bundled Qt5. There is a bug report for it, but no one else has figured out the cause...

Re: rapid photo downloader segmentation fault

So I just updated my system again and realized the problem still persists. I also made a short comment about the still-persistance in the launchpad-bug-ticket.

My current way of working around it is like eschwartz described:

1.

sudo pacman -Syu

(2.

sudo pacman -S rapid-photo-downloader

)
3.

pip install --force-reinstall PyQt5

I really wish this would be solved to work the regular way.
