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

You need the Phonon and phonon backend debugging symbols in particular.

reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise.
