Bug 313338

Application: amarok (2.6.0)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-21-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I queued some songs  (.mp3 in majority of cases, sometimes .flac), closed the laptop lid and listened to the songs. Amarok crashed right when it was supposed to switch to the next song.
(No, the hour is late and I haven't tried to check what happens if songs aren't in queue).
Picking a song from playlist seems to work fine, manually switching to the next song (using 'next' media key) doesn't seem to crash it either (that option wasn't extensively tested either).

It used to work fine before I preformed these actions in that exact order:
-update collection
-delete playlist
-create new playlist (drag&drop the collection to the playlist)
-close the program (via 'close' button)
-open program (after a while)

Issue persist after multiple such crashes which keep happening right one after another. If I recall correctly, I've had at least 5 such crashes in the last 20 minutes.

- Distro + DE:

Kubuntu 12.10, running KDE 4.9. 

- Custom settings of the application:

Playlist = music library (6164 songs) on another disk (NTFS partition), queued songs.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
