Comment 1 Alex Merry 2009-05-13 00:08:24 UTC

Comment 4 Mikko C. 2009-06-20 12:11:35 UTC 
I found a way to reproduce the same crash.

1) Activate dynamic playlist and repopulate. A simple random one is ok.
2) Amarok -> Play Media
3) Choose a music file and click on it
4) Amarok crashes most of the times, same backtraces as above
Comment 5 Mikko C. 2009-08-02 15:56:12 UTC 
Can't reproduce this anymore.
