Description p92 2010-07-10 11:44:28 UTC
Application: amarok (2.3.1)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-23-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I was playing with APG in amarock  triggerring several times constraint tester on integrated example3 "Example 3: about one hour of tracks from different artists" then editing example3  adding a new constraint group then clicking on "Prevent duplicate" condition then clicking on the selection box on the right. I don't remember exactly in what order and how many times.
Suddenly amarok and all KDE was unresponsive then amarok crashed.

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