Sentry Crash Report:

Description Robin Rosenberg 2010-04-05 10:02:37 UTC 
Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I initiated a drag-n-drop operation of the MP3-file from a POD-cast in akregator to amarok. 
During the drag-drop I used Alt-Tab to switch applications. There was some lag in the window
switching, possibly due to KDE's composition, so I accidentally tabbed past amarok and both
akregator and amarok crashed as soon as amarok lost focus (my guess) while I attemted to tab to amarok again.

See https://bugs.kde.org/show_bug.cgi?id=233319 for the other side of the crash.
Comment 2 Mikko C. 2010-04-05 13:02:52 UTC 
Should be fixed in Qt already: http://qt.gitorious.org/qt/qt/merge_requests/1119
