Version:           1.8.1 (using KDE 3.5.0 Level "a" , SUSE 10.0 UNSUPPORTED)
Compiler:          Target: i586-suse-linux
OS:                Linux (i686) release 2.6.13-15-default

I repeatedly experience crashes when saving (CTRL-S), but can't reproduce these crashes in every case. Autosave is turned off.

Interestingly, I got the message that the file had been modified by another application (which I think is not true).

Here's the backtrace:

(no debugging symbols found)
