Created an attachment (id=46907) --> (https://bugs.freedesktop.org/attachment.cgi?id=46907) Server log with crash info

Every now and then, the X server will crash on my machine and restart to kdm. I have never seen it happen live so far, it always happened when I was away from the machine for some time.

System is Debian unstable, xserver-xorg-core package version is 1.10.1-2, but the problem has been occuring for some months now.

In the server log, I find:

========== failed to map pixmap: -12
