Bug 257447

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: clocked the fourth option down on a widget (expander? the box with four arrows) and it loaded 'winebrowser' about seven times from one click. Went to terminal and pkilled winebrowser and then desktop went black.

- Unusual behavior I noticed: pretty sure that button is not supposed to load winebrowser even once. Forget what to call it though.

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