X-Server crashes when pressing a key

[Andreas Roth]

The X-Server crashes sometimes, when press the Ctrl or Alt key. After the X-Server is restarted automatically it also crashes when pressing a simple character key.

In the kdm.log i found the following two backtraces:

Do you still get the crash with the latest xserver-xorg-core?

[Andreas Roth (aroth)]

The current version of xserver-xorg on my system is 1:7.3+10ubuntu8. And nvidia-glx-new in version 169.12+2.6.24.12-15.33 is installed and haven't had any problem lately.
