-- Information about the crash:
- What I was doing when the application crashed:
Browsing through avilable wallpapers
I have a lot of desktop widgets on my desktop, like system monitor, network, cpu, harddrive monitor, ram and so on
- Unusual behavior I noticed:
when I was installing some wallpapers it started slowing down
- Custom settings of the application:
not sure....

The crash can be reproduced some of the time.
