Application: amarok (2.5.0)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:I was noticing strange behaviour in Amarok, it continued to complain about database errors... also, I was trying to resize the star section of a song because it would not display correctly and I was unable to make the setting stay neither size nor recommendation. It also would not play a particular song all the way, so I right clicked on the systray icon to quit, then it crashed. Other information: not sure if related, but I used kid3 to tag song.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
