We need a debugging backtrace with 'bt full' in gdb after installing
libgl1-mesa-dri-dbg.

How hard is it to reproduce? I played an entire neverputt game but
couldn't reproduce the problem on r300_dri. It could be related to
https://bugs.freedesktop.org/show_bug.cgi?id=13208 (which is on r300 in
the beginning), or it could be radeon_dri specific.
