[pkg-nvidia-devel] Bug#586774: Random X server crashes

[Marc F. Clemente]

I upgraded to 195.36.31-2 on Aug 26.  No problems.

I upgraded to 195.36.31-3 on Sep 3.  No problems...  Until Sep 12.  Now 
I start getting random crashes again.  This is what Xorg.log says:

Fatal server error:
Caught signal 11 (Segmentation fault). Server aborting

The crashes started happening after I did a routine upgrade to my system 
(apt-get upgrade).  Only a few packages were upgraded:

It does not look like any of those packages should affect X or nvidia. 
What gives?  Where should I start looking?  Any hints would be greatly 
appreciated.

Thanks,
