Backtrace points to Phonon code, reassigning.
Could you please install the debugging symbols for Phonon and the Phonon backend you use? Please see here on how to get a better backtrace: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports Could you please also specify which Phonon backend and version you are using?

Meanwhile I managed to get along with phonon-dbg. Latest Backtrace follows. I have no idea what my "phonon backend" might be. The crash occurs when closing the IRC messenger "konversation".

I think I recognise this backtrace and am pretty sure it's fixed these days in Phonon.... I'll try and double check soon tho'.
Closing for lack of feedback. This is most likely fixed since quite some time now, I can't reproduce this with current KDE 4.10.2
