-- Information about the crash:
- What I was doing when the application crashed:
I have created a custom dynamic playlist with genre search, playcounter=0 and album play. after i pressed refill playlist, amarok crashed. if i want to start amarok now, it constantly crashes on startup too. the crash report is from the startup crash.

Thanks for the report.

As a first work around please delete (or edit) the file in ~/.kde/share/apps/amarok/dynamicplaylist.xml

New crash information added by DrKonqi

I have to start Amarok several times before it does not crash. I use it to play musik via Ampache.

Comment 10 Myriam Schweingruber 2012-02-23 06:37:31 UTC

Jan, please upgrade your Amarok 2.3.0 is completely outdated.

Comment 12 Matěj Laitl 2012-05-09 11:27:45 UTC

Reporters, please test attached patch and report whether it fixed the crash or not. It should apply cleanly both to current git and Amarok 2.5. I suggest asking on #amarok on IRC to get advice on how to patch and build Amarok from sources.

Comment 13 Julien Bigot 2012-05-25 12:40:12 UTC

Using amarok 2.5.0 (package 2.5.0-2 from debian) I can no longer reproduce the crash I reported in bug #290867 . Echonest test doesn't block the playlist generation anymore.

Comment 14 Matěj Laitl 2012-05-25 21:08:18 UTC

Nobody seems to be able to reproduce this bug now, it could have been recently fixed Qt bug perhaps. The patch was rather theoretical so I'm not going to apply it.
