-- Information about the crash:
If I clicked on wallpaper it crashes evertime. Earlier I had it set to the globe wall paper and all of a sudden the earth shrunk a little. Not sure if that is supposed to happen.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
