This might be a real bug on its own, but why are you using the software rasterizer?

I see that the new mesa 8.0.3 bugfix release includes a couple fixes to the drisw code. I wonder if this is the bug you're seeing.

Dave Airlie:
    glx/drisw: avoid segfaults when we fail to get visual
    drisw: fix image stride calculation for 16-bit.

I've posted mesa 8.0.3 to this PPA. Please install it, reboot, and re-test and see if you can still reproduce the crash. If you're able to test it long enough to convince yourself that the crash is gone, please reply here indicating so. We may be able to roll out this fix for precise-proposed as an SRU.

Some tips:

  * Report X.org bugs via the command: `ubuntu-bug xorg`

  * Test against the latest development Ubuntu. http://cdimage.ubuntu.com/daily-live/
    Bugs marked as affecting the development version tend to get priority attention.

  * The `xdiagnose` utility has functionality for enabling debugging and
    analyzing a few common X problems.

  * Tag your bugs with the Ubuntu versions you have reproduced the issue in.

  * See https://wiki.ubuntu.com/X/Reporting for tips on writing good bug reports.
