-- Information about the crash:
- What I was doing when the application crashed:

I have serveral apps running. 
Desktop 1: Firefox with two windows, Thinderbird and other stuff
Desktop 2: FireFox with one window, same instance as of Desktop 1, Gimp

Now I am at desktop 1 and try to change behavior of the WindowList on the bottom. I like to see only the windows related to the current desktop. After I changed the behaviro Plasma crashes.
