[SOLVED] segmentation fault in onboard

Hi. I use Arch with the onboard virtual keyboard in a tablet (no physical keyboard). Today I've updated arch:

[2012-10-17 14:40] upgraded system-config-printer-gnome (1.3.11-1 -> 1.3.11-2)

Now onboard refuses to work. When I try to run it I received a cryptic message:

onboard
[1]    726 segmentation fault (core dumped)  onboard

Tested with the new onboard 0.98.1-1 from repo. I also built onboard from the trunk version (adapting current PKGBUILD). No luck, segmentation fault in all cases.

I also tested with older onboard versions: onboard 0.98.0-2 and a trunk version I built before today's update (based on old onboard PKGBUILD). I received a different error in those cases:

onboard
Traceback (most recent call last):
  File "/usr/bin/onboard", line 12, in <module>
    from Onboard.Exceptions import chain_handler
ImportError: No module named 'Onboard'

There are lots of updated packages and I don't know which one causes those problems. May be updated ibus?

Any suggestion? I really need help, this problem is crucial for me (my tablet is useless without a virtual keyboard). Thanks.

Re: [SOLVED] segmentation fault in onboard

I've used gdb to debug the error, but honestly I can't understand a word: http://pastebin.com/xXgCxSX1

Re: [SOLVED] segmentation fault in onboard

I've located the packages that causes the problems. I've Downgraded python-3.3.0 to 3.2.3, and python-cairo-1.10.0-2, python-dbus-1.1.1-2, python-gobject-3.2.2-2 and python-virtkey-0.61.0-2 to previous *-1 packages and onboard has revived.

Maybe onboard is not ready to python 3.3. Marked this problem as solved.

Re: [SOLVED] segmentation fault in onboard

Hi altercation. Downgrading python 3.3.0 to 3.2.3 is a temporary solution, I wish someone find a better one.

I've file bugs in onboard and in Arch:

Re: [SOLVED] segmentation fault in onboard

Fixed by installing python-gobject 3.4 (in Testing repo at present day) and onboard 0.98.1-2. So there's two posibilities to fix it, downgrade to python 3.2 or upgrade python-gobject to 3.4
