Bug Description
Ubuntu 11.10 crashes on an almost daily basis, and I'm doing various different things when it does so, so I can't easily identify what's to blame. Sometimes it happens when I'm in Firefox, sometimes Thunderbird, sometimes in a Virtualbox machine running Windows Xp. But it always happens the same way: it goes instantaneously to the black screen of death (which looks like a logout) and thence to the login screen.
My Xorg.0.log.old has the following entries at the end of the log after every crash:
[ 1214.793] Segmentation fault at address 0xb2536008
[ 1214.793]
Caught signal 11 (Segmentation fault). Server aborting
[ 1214.793]
Please consult the The X.Org Foundation support
at http://
for help.

I have no idea if it's helpful, but my ~.xsession-errors has a lot of these errors:
WARN 2012-02-21 11:03:27 glib.glib-gobject <unknown>:0 instance of invalid non-instantiatable type `(null)'
and a lot of these:
WARN 2012-02-21 10:12:05 glib <unknown>:0 Unable to fetch children: Method "Children" with signature "" on interface "org.ayatana.
I'm happy to give more info, but I'd need guidance as to what's relevant.
