[Original Report]
I get crashes of the Xorg server if I press the "Del" key. This happened three times recently and seems to be repeatable. The system is an up-to-date Kubuntu 8.04.
The dmesg says:
[ 754.699253] Xorg[5444]: segfault at 000001a4 eip 0818fa3a esp bfa98800 error 4
[ 866.241862] Xorg[9589]: segfault at 000001a4 eip 0818fa3a esp bfd02030 error 4
[ 1039.389615] Xorg[10174]: segfault at 000001a4 eip 0818fa3a esp bfd978d0 error 4
The first two crashes happened with a Java program while saving a file. I placed the cursor in the middle of the default filename and pressed the "Del" key. As here were no more characters to delete left, Xorg crashed.
The third crash happened with Seamonkey while editing the Ubuntu bug report search query.
Note: Special on my system is, that I have a Wacom Bamboo connected.
My xorg.conf will follow.
