Application: amarok (2.3.0)
KDE Platform Version: 4.4.80 (KDE 4.4.80 (KDE 4.5 Beta1))
Qt Version: 4.7.0
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Steps to reproduce:
Open amarok
Load files from playlist or select from files
Double click on item in playlist to start playing (doubleclicking the file in the library plays it, the same holds true for clicking the play button)

Here is the debug output from amarok:
