A couple of weeks ago I ranted about being able to crash about any available music player on Fedora, and the gazillion bugs I filed for that ..
At last the the problem is solved, as mentioned in https://bugzilla.redhat.com/show_bug.cgi?id=657971#c17
this is most probably a bug in ffmpeg which is provided by rpmfusion. and which is solved by installing gstreamer-plugins-ugly
At least it works for me :)
