Comment 1 Myriam Schweingruber 2010-12-20 14:14:42 UTC 
Sorry, but your backtrace is not useful, as you are lacking debugging symbols. If you can reproduce this bug, please check here on how to get a valid backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Since you are using Kubuntu, you will need amarok-dbg and phonon-dbg at least, ideally you should also have kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg. That should cover most of the crashes.
Comment 2 Jonathan Kolberg 2010-12-20 14:23:14 UTC 
I’m installing these. If I see that crash again I’ll send the backtrace.

Regards Jonathan
Comment 3 Myriam Schweingruber 2011-01-10 18:29:57 UTC 
Any news on this?
Comment 4 Jonathan Kolberg 2011-01-10 19:13:51 UTC 
Not happening. Maybe it was fixed?
Comment 5 Myriam Schweingruber 2011-01-10 21:45:21 UTC 
Thank you for the feedback, closing as fixed. Feel free to reopen if you can reproduce it with the upcoming Amarok 2.4 or later.
