Comment 36 for bug 241145

I think I'm seeing the same bug, except that in my case it seems to be related to the Adobe (binary) flash plugin for Firefox - of course no user application (binary or not) should be able to cause the X server to crash.

This is with xserver-xorg on Ubuntu (Hardy) 1:7.3+10ubuntu10.2 on x86_64 on an "Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)" (Chipset: "945GM")

The Ubuntu bug for my problem is here:

https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/241145

Just so that it's all in one place, the other Ubuntu bug that I think this is the same as is here:
