Bug#366292: xlibmesa-dri broken image and SEGV with ATI Radeon 7000 IGP

[Gustavo HC Silva <ghcsilva@ufl.edu>]

Package: xlibmesa-dri
Version: 6.9.0.dfsg.1-6

When using acceleration and direct rendering the image comes-up all 
garbled-up and sometimes the programs quits due to a SEGV error.

This error can be easily reproduced using blender3d or gmsh. Before 
selecting any objects blender or gmsh the image is fine. After selecting 
any object the image becomes completely garbled. If you rotate the 
object view in gmsh repeatedly it will throw the SEGV error.

If you turn of direct rendering the two programs work fine. The 
xlibmesa3-dri-trunk package with XFree86 does not produce this bug.

I'm using Debian testing with kernel 2.6.16.11.

Here is my xorg.conf if it helps:
