Description Lennart Preuss 2011-04-30 17:24:05 UTC 
Application: amarok (2.3.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-28-generic x86_64
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
I have a Dynamic Playlist with one proportional, "Play Count Less than 1". If I set the proportion to 100%, Amarok crashes on exit every time.

I'm not sure exactly what the magic limit for not crashing is. However, 92% is OK and 96% isn't.

The crash can be reproduced every time.

 -- Backtrace:
Application: Amarok (amarok), signal: Aborted

You should upgrade your Amarok version, 2.3.0 is rather old and outdated, current is 2.4.0 and 2.4.1 is around the corner.

See also http://www.kubuntu.org/news on how to get a newer Amarok version for your distribution.
Comment 2 Myriam Schweingruber 2011-07-17 22:19:41 UTC 
Closing for lack of feedback. Feel free to reopen if you can still reproduce
this with Amarok 2.4.2 beta 1 or later and provide the necessary feedback.
