Comment 24 for bug 362883

Austriaco, are you using any custom repos? You have mesa 7.3 but intrepid shipped with mesa 7.2 and jaunty with mesa 7.4 (also note that odd number mesa versions are development releases, i.e 7.1 and 7.3 and 7.5 etc.. you should use a even numbered release for everyday use)

This page the different mesa versions we have in the various active ubuntu spins right now:
https://launchpad.net/ubuntu/+source/mesa

Also, in general... the mesa 7.4 bug that printed the error in the original bug report is harmless. if you study the upstream patch you'll notice that the bug was a trivial one that could not possible have caused a hang or so. I'm talking about:
Mesa 7.4 implementation error: bad wrapMode in clamp_rect_coord_linear

So that part of the error message was a false positive, we need to be looking for some other clue.
