x hangs while using glx, and compiz segfaults

[Rubin]

Binary package hint: compiz

Repeatable; seems to trigger while using any big textured 3d program, such as second life, or scorched3d. 3d image is full of static, and redraws flickering whenever any other windows under it redraw. Finally x hangs, attempts to restart over and over and finally hangs the entire system. I belive it may be related to #120834.
