Comment 3 Myriam Schweingruber 2011-01-16 19:14:24 UTC

Sorry, but your backtrace is not useful, as you are lacking debugging symbols.  Dr. Konqi allows you to install the missing debugging symbols when it starts.

Created attachment 56146 [details]
New crash information added by DrKonqi

amarok (2.4.0) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:

I selected a song to play, then after a few seconds I selected another one and Amarok crashed.

Git commit 81fd6990a4684202571baebc92415ccfbda62651 by Andreas Hartmetz.
Committed on 25/03/2011 at 22:03.
Pushed by ahartmetz into branch 'master'.

Don't dequeue tracks hidden from view while searching, second try.

This time while keeping bug 263308 closed.
We remove a track from the queue when it is removed from the *bottom*
model in the model stack, i.e. permanently.
