Application: plasma-netbook (0.1)
KDE Platform Version: 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3))
Qt Version: 4.6.1
Operating System: Linux 2.6.32-12-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
I have the newsfeed widget in a left colomn and the note widget in the right column of the newspaper activity. Since it is impossible to tell where the bottom of the note widget is (there is no "square" around the widget) I wanted to change its color. Unfortunately plasma-netbook alwyas crashes when I hit OK in the settings dialogue.

I am on kubuntu lucid with kde rc 4.4 rc3

The crash can be reproduced every time.

 -- Backtrace:
