The kernel log shows this: Jan 13 20:43:41 duff kernel: [204105.153174] divide error: 0000 [1] SMP
However that's not enough to troubleshoot from. Could you please reproduce the issue and attach the Xorg.0.log[.old] from after that? As well, we will need a full backtrace; directions for doing this are available at http://wiki.ubuntu.com/X/Backtracing.
