Application: amarok (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
New install of kubuntu 12, about 36 hours old. I opened Amorak early on to test if it could play Wavpack files (which it did). It then sat in my menu bar, through various reboots of the system as I configured it. When I finally opened it from the menubar and selected 'Local Music' in the sidebar, it crashed. Amorak has all its defaults--I don't recall changing anything.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
