-- Information about the crash:
- What I was doing when the application crashed:
Plasma Desktom crashes with no obvious reason. Then it restored.

- Unusual behavior I noticed:
I noticed Amarok to be closed though I didn't do that.

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