Bug 59280

After running out of memory (at least creating some pressure), programs using Clutter such as GNOME Shell, Mutter and GNOME Documents crash on start; once the problem happens it does not disappear. I'm able to reproduce this problem reliably on Fedora 18 with Xorg server 1.13.1, i915 driver 2.20.17, kernel 3.7.1, Mesa 9.0.1 and Clutter 1.12.2.

My GPU is an Ironlake Mobile:
00:02.0 VGA compatible controller [0300]: Intel Corporation Core Processor Integrated Graphics Controller [8086:0046] (rev 02) (prog-if 00 [VGA controller])

Another person also reported the same crash also with an Ironlake.

Top of the backtrace is:
