Bug 302047

Application: plasma-desktop (0.4)
KDE Platform Version: 4.8.90 (4.8.90)
Qt Version: 4.8.1
Operating System: Linux 3.4.0-3-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: I wanted to change the battery plasmoid to show the percentage of it's capazity.  When applying the setting, the crash occured. It can reproduced in that way. There is also to note that the icon of the plasmoid looks a little strange blown up in size since I installed Beta2. There might be a relationship with this phenomena.

The crash can be reproduced every time.

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