--- Comment #2 from Roderick Colenbrander thunderbird2k@gmx.net 2008-01-20 16:08:07 --- It might be related to bug 11210 which is testing the shader capabilities of videocards. The reason I think it is related is because in your case it crashes in the shader code too and second Eric Anholt works on the intel video drivers.
