Public bug reported:

Binary package hint: libgl1-mesa-dri

When trying to start any OpenGL-based program it immediately crashes
with the output on stdout:

"brw_misc_state.c:290: emit_depthbuffer: Assertion 'region->tiling != 1'
failed."

This is on a Lenovo X61 tablet/notebook with a i965 chipset (GPU: intel
GMA X3100). The affected file comes from
mesa/drivers/dri/i965/brw_misc_state.c

The package in question is libgl1-mesa-dri 7.8.1-3ubuntu2

Tried it with these programs, which all fail with the same error stated above:
* glxgears
* compiz
* mutter
* unity (as mutter-plugin)
