-- Information about the crash:
- What I was doing when the application crashed:
I pressed RMB, then went to click elsewhere on the screen b/c it wasn't what I meant to do. Immidiate crash.
- Unusual behavior I noticed:
Prior to crash, I have repeated errors - it has problems loading wallpapers in desktop1, even tho the wallpapers there - I have to go "next wallpaper" to get one to display.
- Custom settings of the application:
Multiple desktops (4 screens in 1 column), cube animate, wobbly window.

The crash can be reproduced sometimes.
