Product: [Applications] amarok Reporter: Matěj Laitl <matej>
Component: Collection BrowserAssignee: Amarok Bugs <amarok-bugs-null>
Status: RESOLVED FIXED    
Severity: crash CC: bart.cerneels, kfunk
Priority: NOR    
Version First Reported In: 2.4-GIT   
Target Milestone: 2.4.2   
Platform: Gentoo Packages   
OS: Linux

Sentry Crash Report:

Description Matěj Laitl 2011-06-08 17:49:58 UTC 
Application: amarok (2.4-GIT)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 3.0.0-rc1-00049-g1fa7b6a x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- How to reproduce:
1. Add a file that is not in your collection to your playlist
2. Drag that track from playlist into Local Collection

- Actual results:
Amarok crashes

- Expected results:
It would be great if Amarok showed copy here/move here selection if no Shift/Ctrl key was hold durring dropping (Dolphin behaviour) and then present Copy to collection/Move to collection dialog.

This is related to http://commits.kde.org/amarok/fffc1ea983281e6cb1f6ce2129f046e598fe01c4 that enabled drag&drop.

The crash can be reproduced every time.
