Description Milan Bouchet-Valat 2013-01-10 22:15:07 UTC 
This crash has been reported twice on Fedora 18 with gnome-shell 3.6.2.

In my case, it happened under memory pressure, so it may well be related (memory corruption?).

My GPU is an Intel Ironlake (i915 driver), but we lack statistics to know whether it matters or not.
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller])

Do you have any idea whether this may be a bug in the Shell, in Mutter in Clutter, in Mesa, in the drivers...? Mutter also crashes on start.

Silly me, I didn't even look at /var/log/messages:

So it looks like a GPU/drivers problem. I'd still like to hear from you if you have any idea that might help debugging (Metacity runs, Mutter does not, so there's something with compositing).
Comment 2 Milan Bouchet-Valat 2013-01-12 16:57:00 UTC 
Sorry, this is a known bug in the Intel driver, which crashes Clutter apps. https://bugs.freedesktop.org/show_bug.cgi?id=55984
