This bug was originally reported downstream here:

I just experienced a completely spontaneous Xorg crash using radeon driver.
Seems EXA-related according to the stack trace. I wasn't doing anything other
than typing an email in Evolution (no videos, no OpenGL-apps other than Compiz
itself).

- Ubuntu Jaunty RC (tracking/current)
- Running Compiz
- Using radeon Xorg driver (xserver-xorg-video-radeon 6.12.1-0ubuntu2)
- Kernel linux-image-2.6.28-11-generic 2.6.28-11.41 (Ubuntu)
- Mesa 7.4-0ubuntu1
- Xorg 7.4~5ubuntu18

Hardware:
- ATI X1400 Radeon Mobility, 128MB RAM
- Intel Core Duo 2GHz, 2GB RAM

Here is the backtrace:
