Bug detailed description:
-------------------------
With compiz enabled, gnome-session startup fails and will crash X. OS is Fedora 11. If compiz disabled, gnome-session works well. It crashed X with the following message: 
compiz: intel_regions.c:193: intel_region_alloc: Assertion `aligned_pitch == pitch * cpp' failed. 
There is no such issue on mesa master branch. And it may be the same cause with #27030. 

Reproduce steps:
----------------
1.xinit&
2.gnome-session&
