Description Jan de Groot 2010-03-24 14:03:50 UTC

To reproduce:
- add two keyboard layouts in keyboard preferences. In my case, this is USA and USA International (with deadkeys)
- right-click the notification area thingy that shows up, click "Show Current Layout"
- watch gnome-settings-daemon crash

Additionally, when I restart gnome-settings-daemon after the crash, GNOME crashes back into gdm. I think that's a different bug though. I haven't found out the crashing application for that issue yet.

Some part of the backtrace:

+ Trace 221070

#47 gtk_widget_show
from /usr/lib/libgtk-x11-2.0.so.0
#48 popup_menu_show_layout
from /usr/lib/gnome-settings-daemon-2.0/libkeyboard.so


I'll add some more useful backtrace information later, as I don't have debug symbols at hand at this moment.

Comment 1 Edward Hervey 2010-03-27 12:11:18 UTC

wouldn't this be the same issue as bug #613621 ?

Comment 2 Sergey V. Udaltsov 2010-03-27 12:32:09 UTC

Not sure. We need detailed backtrace.

Comment 3 Jan de Groot 2010-03-27 12:55:45 UTC

Some more information, glib, gtk+ and gnome-settings-daemon have been compiled with -O0 -g now:

Comment 4 Sergey V. Udaltsov 2010-03-27 13:07:20 UTC

I'd say it is different from #613621.

But still odd. What's the distro?

Comment 5 Jan de Groot 2010-03-27 13:11:42 UTC

Some more information about the packages used:
gnome-settings-daemon 2.29.92
glib 2.24.0
gtk+ 2.20.0

And another backtrace, using G_DEBUG=fatal-criticals:

Comment 6 Jan de Groot 2010-03-27 13:12:44 UTC

Distribution is Archlinux, using the gnome-unstable repository. I'm the GNOME maintainer of this distribution, so if you need anything, just ask. I'll be happy to provide all the information you need.

Comment 7 Sergey V. Udaltsov 2010-03-28 08:24:02 UTC

What I'd try is commenting out the actual drawing widget from the code.
Also, could you double-check that show-layout.ui is installed properly?

Comment 8 Jan de Groot 2010-03-28 12:15:37 UTC

This was caused by a bug in libgnomekbd. After applying the patch from bug 612341 to libgnomekbd, I can't reproduce t he crashes anymore.
