Description michael.teubner 2010-03-02 08:34:10 UTC 
Application: amarok (2.2.90)
KDE Platform Version: 4.4.00 (KDE 4.4.0) "release 224"
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.1-desktop i686
Distribution: "openSUSE 11.2 (i586)"

-- Information about the crash:
When trying to drag a saved playlist to the actual playlist, Amarok crashes.
When I start Amarok and a playlist is playing, then I open the folder 'Playlist Files on Disk' on the left and double click the title. The folder opens and I see one playlist. I double click the playlist. The playlist opens and is playing it's content, actually a web-radio-station. The playlist has two entries. When I try to drag the second entry of the playlist to the actual playlist in the right window, Amarok crashes. 

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