Version:           unknown (using KDE 3.5.0 Level "a" , SUSE 10.0 UNSUPPORTED)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.13-15.7-default

This is a show stopping bug. I cannot write/edit documents using kate/kwrite as this bug is causing a crash every 10 minutes and causes me to lose the data from my last edit.

1. Open a (local) document with kate/kwrite.
2. Wait 1 to 5 minutes. Doing nothing and editing/saving here causes no effect.
3. A dialog appears saying that the file has been modified by another program (when it has not).
4. Click the save button.
5. kate/kwrite will crash with the following bug report:

I also had a similar crash in kpdf when it was set to watch a file for modification and it crashes with a similar trace when the file was modified. I will try to post this I can recreate it.
