Accidently sent this part to Brian directly:

"I just installed the packages from 
https://launchpad.net/~oibaf/+archive/graphics-drivers/ i.e. Mesa 9.2 
(git), llvm-3.2 etc. but I still get the same error.

I will also try it on a local desktop VM with 12.04. Maybe there's just 
something wrong with the cloud VMs."


Ok, I have made some progress now. On my desktop VM with Mesa 8.0.4 and 
regular X server (but also with llvm and LIBGL_ALWAYS_SOFTWARE=1) it 
works! But when I start up xvfb on a different display (:99), change the 
DISPLAY var, the tests are failing again. So it must be somehow related 
to Xvfb. Right?
