Seg Fault in xf86SignalHandler+0x85

[Paul_R]

I'm running x11-base/xorg-server 1.1.1-r4 and once every few weeks I get a seg fault from xorg, particularly xf86SignalHandler, and am dumped to the console. It always happens when I'm away from the computer. I don't see a core dumped anywhere (perhaps I'm not looking in the right place). What's the best way to proceed to try to track down what exactly is going on? Has anyone seen similar problems? I was completely up to data as of a week or so ago, but that doesn't seem to matter as the seg-fault has been going on for a few months. Any ideas are appreciated.

thanks,
Paul
