We can't reproduce this crash on ubuntu platform both 12.10 and 13.04.

The above log is the most weird thing in this case. It has a running X but fail
to do the dri2 authentication. And latter it open the /dev/dri/card0 as master
successfully. This just should not happen. IMO, it's an indicator that there
is something wrong in the system consistency.

No symbol information, it's hard to analysis.

I just discussed with Junyan. And he may help to investigate this issue on your machine
directly. Thanks.
