Trying to drag an item of a level 2 from the collections pane from a scripted service fails, popping up an error saying that a variable generated for level 0 items from level 1 items' callbackData is undefined. Trying to drop the item on the playlist freezes Amarok. This does not occur if all the level 1 items under the level 2 item have been expanded already. Looking at the debugging output, it appears that Amarok tries to drag all the level 0 items under the level 2 item without getting the level 1 items. This fails because level 0 items are generated from the callbackData of level 1 items.

KCrash: Application 'amarok' crashing...
KCrash: Attempting to start /usr/libexec/kde4/drkonqi from kdeinit
KCrash: Connect sock_file=/home/be/.kde/socket-localhost.localdomain/kdeinit4__0

Reproducible: Always

Steps to Reproduce:
1. Write a scripted service with at least 3 levels.
2. To populate level 0, refer to callback data from level 1 items.
3. Drag a level 2 item.

Actual Results:  
Amarok does not populate the level 0 items correctly because it never populated level 1.

Expected Results:  
All level 0 items with playableUrls are dragged with the level 2 item.
