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 jorge salgueiro 2010-10-22 19:39:25 UTC
Created attachment 52775 [details]
New crash information added by DrKonqi

Now with dbg symbols, sorry for the other report. Amarok crashes when a song starts to play

Backtrace from comment #2. Please always paste backtraces inline, else it is not searchable.

I'm new at this..
Comment 5 Myriam Schweingruber 2010-10-23 14:03:41 UTC
The crash lies in Qt, not much we can do about that, sorry. I strongly suggest you check if you have the released Qt 4.7.0 version and not the beta or RC version (aptitude show libqtcore4).
