The only related backtrace that I found in the upstream bugzilla is at
https://bugs.freedesktop.org/show_bug.cgi?id=8588
This bug is already one year old and it never got any reply. The
corresponding downstream bug has been marked as fixed for a while (patch
included in Mesa 6.5.3) so it's probably not the same problem in the end.
You still have no easy way to reproduce this? Could you enter 'bt full'
instead of 'bt' in gdb next time?
