Comment 1 Matthias Clasen 2011-08-25 00:56:25 UTC 
Could well be the same cause as bug 657241, X calls from multiple threads without proper protection.
Comment 2 Allison Karlitskaya (desrt) 2011-09-06 14:34:15 UTC 
This looks like a GSettings bug.

commit 27fbaf371278e792c79a3478c2282e43f12472f5
Author: Ryan Lortie <desrt@desrt.ca>

    GSettingsBackend: emit changes to correct thread
    
    When g_settings_apply() is called on a delayed settings backend and
    there is a D-Bus error when communicating with dconf-service, recent
    versions of the dconf GSettingsBackend call a function in GLib that
    improperly delivered the signal directly instead of using
    g_main_context_invoke().
    
    This patch fixes this function to route in the same way as the others so
    that the signal is dispatched in the proper GMainContext.




Seb is going to ship this as a vendor patch to the just-released 2.29.90 to see if it fixes the problem.  If it works, I'll backport to glib-2-30 and close this bug.
Comment 9 Allison Karlitskaya (desrt) 2011-09-18 14:07:56 UTC 
I guess no news is good news from the Ubuntu guys.  I applied this patch to glib-2-30 branch as well.
