I've seen this crash again, several times actually, but not everytime.

plasma-desktop (0.4) on KDE Platform 4.9.00 using Qt 4.8.1

- What I was doing when the application crashed:
1. Opened the activity manager.
2. Clicked "add widgets".
3. Clicked "Activities".
4. Crash.
- Unusual behavior I noticed:
1. Background of Activity Manager is partly translucent instead on opaque.
2. Switching Activities results in the wallpaper turning 100% white.
- Custom settings of the application:
Nothing much.
