Comment 1 Jussi Kekkonen 2011-10-18 07:30:49 UTC 
Apparently crash does not occur when there is pattern selected.
Comment 2 Christoph Feck 2011-10-18 09:20:06 UTC 
If this is reproducible, could you add a backtrace with kdeplasma-addons-dbg installed?
Comment 3 Jussi Kekkonen 2011-10-18 09:48:16 UTC 
Reproducible, steps to reproduce:

1) Make sure there is no pattern already selected (in ~/.kde/share/config/plasma-desktop-appletsrc [Containments][1][Wallpaper][pattern] has no pattern= )

2) Go to Desktop Settings of Plasma Desktop -> View -> Wallpaper: Pattern

3) Do not select any pattern from the list available, do only try change one of the colours

4) Select some colour and exit the "Select colour" dialog by pressing ok.

5) Cräääsh
