Application: amarok (2.3.2)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was deleting MP3 files from a connected iPod Mini by selecting the Genre and clicking "Delete" in the context menu. The progress bar in the bottom right didn't indicate any progress (kept displaying "0%", even after a few minutes). But the selected Genre was already gone in the tree view. After attempting to delete the next Genre, Amarok crashes on me. This is reproducible, although it seems that after a restart of Amarok the MP3 files on the iPod are gone (i.e they are not visible in the tree any more and the free size is growing...).

The crash can be reproduced every time.

-- Backtrace:
