Description Thierry Vignaud 2011-01-17 14:01:28 UTC 
Description of problem:
firefox4 crashes in mesa-7.10 with kernel-2.6.37 with nouveau driver (but in soft rastering code).
Soft rendering was forced by running firefox with another user that has no access to /dev/dri/card0.

Version-Release number of selected component (if applicable):
Tested on Fedora with:
mesa-dri-drivers-7.10-0.18.fc15.x86_64
firefox-4.0-0.17.beta9.fc14.remi.x86_64
kernel-2.6.37-2.fc15.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Set 'layers.acceleration.force-enabled' to true and 'layers.acceleration.disabled' to false in firefox4 (using about:config)
2. restart firefox
3. firefox prints "failed to create drawable" thenl segfaults in mesa
  
Actual results:
Segfault

Expected results:
soft rasterizer should not make firefox segfault
