Hi,
After upgrade of KDE to 4.8 (rc2 currently), drag and drop from collection does not work correct most of the time. The middle panel changes, like for DnD, but it stays inactive - when I drop selection on option "Add to playlist" - selection is not added to playlist, but sent to another running application - konsole, firefox... . Amarok is maximalized, so it is not possible to drop it on these applications. The same issue is when I'm trying to drop selection on playlist.

Reproducible: Sometimes

Steps to Reproduce:
1) Drag something from collection
2) Drop it in middle panel on "Add into playlist" option or directly in playlist

Actual Results:  
Selection is not added to playlist. As a bonus, you can find it in another running application like konsole, firefox. 

Expected Results:  
Selection is added to playlist

It started after upgrade of KDE to version 4.8 (beta) and works incorrectly till now. Amarok compiled from git yesterday.

Interesting is, that sometimes it works correctly and later again does not work. Unfortunately I don't know, what is triggering this.
