Description shaddowy2 2012-11-22 22:35:47 UTC

Application: amarok (2.6.0)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
While trying to reproduce Bug 308703 I found the following crash:

- What I was doing when the application crashed:
1. Start Amarok
2. Go to "Saved playlists", merged view and create a new playlist folder with a click on the icon
3. Drag on of your already created playlists (file, didn't try for database playlists) onto the newly created folder.
(4. Nothing happens, the playlist isn't moved / copied to the folder) --> should be solved with when bug 308703 gets fixed.
5. Exit Amarok and watch it crash

The crash can be reproduced every time.
