If you eject a cd after playing tracks from it and then select edit track details including some cd tracks (I was trying to see the length of a subset of the playlist) amarok will crash.

- Insert cd
- Add cd tracks to playlist (with other tracks)
- play cd and after completion
- eject cd (from within amarok) tracks don't grey out
- select tracks including a cd track
- try to select 'edit track details' (from mouse menu)
- amarok will immediately crash

Repeatable - here's the relevant bit of the traceback
