-- Information about the crash:
- What I was doing when the application crashed:
I had quit Amarok and was moving to another application (Firefox). The traceback looked similar but not identical to others with similar issue, so I did not mark as duplicate.

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