Comment 1 Matthias Runge 2012-11-05 12:48:32 UTC
Great, that is seems to be just me.

I've found some backtrace:
Gtk.py:1624:<module>:RuntimeError: Gtk couldn't be initialized

Traceback (most recent call last):
  File "/bin/firewall-config", line 22, in <module>
    from gi.repository import Gtk, GObject
  File "/usr/lib64/python2.7/site-packages/gi/importer.py", line 76, in load_mod
ule
    dynamic_module._load()
  File "/usr/lib64/python2.7/site-packages/gi/module.py", line 244, in _load
    overrides_modules = __import__('gi.overrides', fromlist=[self._namespace])
  File "/usr/lib64/python2.7/site-packages/gi/overrides/Gtk.py", line 1624, in <
module>
    raise RuntimeError("Gtk couldn't be initialized")
RuntimeError: Gtk couldn't be initialized

Local variables in innermost frame:
Box: None
_callable: None
Container: None
LinkButton: None
SizeGroup: None
HScrollbar: None


When using gdm as login manager, the system works as expected.

Comment 2 Rex Dieter 2012-11-05 12:55:44 UTC
any abrt report and/or backtrace could help...

Comment 3 Matthias Runge 2012-11-05 13:03:12 UTC
core dump:
http://www.matthias-runge.de/fedora/coredump
pyhook dir from abrt:
http://www.matthias-runge.de/fedora/pyhook.tar.gz

Comment 4 Rex Dieter 2012-11-05 13:16:01 UTC
That looks more like a crash report for firewall-config, not lightdm.  ??

Comment 5 Matthias Runge 2012-11-06 07:35:40 UTC
I'm very sorry, I must have mixed that up.

That dir containing the coredump etc. is here:
http://www.matthias-runge.de/fedora/ccpp.tar.gz

cat cmdline 
/usr/sbin/lightdm-gtk-greeter

cat package 
lightdm-gtk-1.3.1-1.fc18

Comment 6 Matthias Runge 2012-11-21 11:21:45 UTC
I could this error reproduce in a kvm virtual machine, but not on real hardware.

Comment 7 Matthias Runge 2012-11-22 08:49:26 UTC
Since I even can not reproduce this error in a freshly created vm, I'm closing this bug as notabug. Thanks

Comment 8 Matthias Runge 2012-11-23 08:49:53 UTC
I could narrow this crash to this update.

https://admin.fedoraproject.org/updates/FEDORA-2012-16107/xorg-x11-drv-qxl-0.1.0-1.fc18

Downgrading to an earlier version fixed the issue.
