Application that crashed: amarok
Version of the application: 2.2.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Amarok 2 crashes after various actions.  It will most frequently crash after moving a file to the collection but has also crashed when removing a file from the playlist, after a file finishes playing and when closing.  No particular sequence of actions seems to provoke this behavior and I have been unable to reliably reproduce the crash.  I does occur most often when I am ading new file to my collection.  My action here are to:

1. rip a CD to a folder on my desktop
2. Using Amarok 2, navigate to the folder
3. Using Amarok 2, edit the tags for track 1
4. Using Amarok2, move the file to my collection
5. Repeat steps 3 and 4, incrementing the track number until I have finished adding the album to my collection

At some point during this sequence Amarok will crash.  One observation to be noted is that the Amarok window will always grey-out during the copy, which seems to take an inordinate amount of time (often >30 seconds) and the progress bar on the lower right will increment to 2% and stay at that point until the move is completed or Amarok crashes. After a crash I find that the move had completed successfully regardless of Amarok's response (still running and ready for my next action or crashed).
