Bug 213607

May be duplicate of bug 207579.  I get a reproducible crash when I do this
1. Add audio CD track to playlist (which plays automatically)
2. Double click the track in the playlist once or twice

This is a crash in Phonon, not in Amarok, bout your backtrace lacks some information. Could you please install the phonon-dbg package and try reproducing this again to get a better backtrace?

Created attachment 38187 [details]
kcrash stack trace

When I installed phonon-dbg, it also pulled in the dependency libphonon4.  After that, the crash didn't happen so easily, but I still have a new stack trace as requested

Backtrace from comment #3:
