Comment 1 Myriam Schweingruber 2011-04-21 12:13:45 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 Dev Ghai 2011-04-25 03:44:46 UTC 
I have installed all the requested packages and it is still not generating a useful crash report. Most of the time now the crash handler does not even come up. I've been able to reproduce the bug consistently. I am in the process of recording my screen and uploading the video. Hope that will help.
Comment 3 Myriam Schweingruber 2011-05-04 12:24:40 UTC 
You can try running it in gdb to get a backtrace. Type the following in a terminal:

gdb amarok

run -d --nofork

once it crashes, type this

bt

and paste the last results.
