Bug#648159: libglib2.0-0: GLib-GObject-CRITICAL triggers Fatal IO error 11

[Skippy le Grand Gourou]

Package: libglib2.0-0
Version: 2.24.2-1
Severity: critical
Justification: causes serious data loss


Since a while I experience regular half-freezes on my up-to-date Debian Squeeze
install with Gnome 2.30.

By "half-freeze", I mean either of the two following cases (both can happen) :
- the content of the active window is still accessible (the main window usually
being Firefox, this means that I can continue to navigate through links and
HTTP forms), but cliquing on the window menu as well as on the gnome-panels has
no effect, and keyboard shortcuts such as ALT+TAB to switch the active window
won't work either ;
- the active window menu and the gnome-panels are accessible, but the content
of the active window is not (this means that for Firefox I am not able to
navigate anymore).

In both case I have to restart the X session (by Ctrl+Alt+Backspace).

Attached is the .xsession-errors file after 5 such a freeze.  I set cron to add
the date and time every minute or so to check that the issue was indeed
triggered by the GLib warnings.  As most of the time these warnings are issued
by Firefox I first thought it was the culprit, but on the last example you can
see that the trigger is gnome-panel.

I use no xorg.conf.  There is nothing relevant neither in dmesg nor in /var/log/* 
apart from Xorg.0.log.  Xorg.0.log, .xsession-errors after 5 freezes and 
lspci -vvv output are available on the upstream report
(https://bugzilla.gnome.org/show_bug.cgi?id=663647).  As quoted from there :
"2.24 is likely not supported in upstream anymore - too old. Might make more
sense to report this to Debian Bugzilla..."
