Comment 1 Myriam Schweingruber 2011-05-26 09:41:04 UTC 
Could you please upgrade to Amarok 2.4.1 and try again? See also http://kubuntu.org/news
Comment 2 Kevin Njeru 2011-05-27 18:16:20 UTC 
I installed to the version recommended, still did not fix the problem, which now occurs always when shutting off.
Comment 3 Myriam Schweingruber 2011-05-29 10:26:31 UTC 
Could you please provide a new backtrace? This is not necessarily the same as there were quite some changes since 2.4.0
Comment 4 Myriam Schweingruber 2011-07-15 08:46:04 UTC 
Closing for lack of feedback. Feel free to reopen if you can provide the necessary information and can reproduce this with Amarok 2.4.2 beta 1 or later
Comment 5 Jannis Liapis 2012-04-20 06:31:46 UTC 
Created attachment 70521 [details]
New crash information added by DrKonqi

amarok (2.5.0) on KDE Platform 4.8.2 (4.8.2) using Qt 4.8.1

- What I was doing when the application crashed: Nothing in particular, just closed amarok and the crash report came up. One strange thing I noticed is that the last 3-4 days amarok icon do not appear in the system tray.

Comment 6 Myriam Schweingruber 2012-04-20 21:40:22 UTC 
Jannis, please do not attach backtraces to reports closed since more than 6 months for versions much older. 
Also your backtrace shows this is not at all the same bug, yours is a duplicate of bug 295951, already fixed in the development branch.
