Bug 205219

Sorry, but your backtrace is not very useful, as you are missing debugging symbols. Please see here on how to produce a valid backtrace:

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

Also, the crash is apparently in Phonon:

#5  0x00007fafc8b027bf in Phonon::MediaSource::type() const () from
/usr/lib64/kde4/plugins/phonon_backend/phonon_xine.so

This might help. I posted the same trace on #205950.

Application that crashed: amarok
Version of the application: 2.1.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I have difficulty getting AmaroK to play a stream set up as a Playlist. It will play from my Collection but sometimes when I load a stream I get the indication that it is playing the stream but no audio. If I quit Amarok when this happens it crashes.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

@ Luke
Your crash appears to look more like bug 191366, according to the crash log. (And actually 207422 is a duplicate of that bug as well, oops.)
Since the original reporter never responded to the request for a better backtrace, I will close this bug as needsinfo.

It is actually a duplicate of bug 180214.
