Bug#690291: Amarok randomly stops playing sound when song automatically changes using phonon-backend-gstreamer

Ok, I'm able to confirm and reproduce this bug here now.  I created my
own debug output and gstreamer is in fact throwing a critical error
silently in the background.

I took an OGG music file. Loaded it into Audacity. Exported it as FLAC
and then put the flac file after the ogg file in the playlist and
Amarok fails to play the flac file.  If you double-click on the flac
file in the playlist then Amarok plays the flac file just fine.

This is really a bizarre bug, but I'm guessing maybe the phonon
gstreamer backend isn't switching gstreamer plugins properly.

Since this bug does not happen with the VLC phonon backend, I've filed
this bug upstream against the gstreamer phonon backend.

You don't need to do any more testing for now, thanks for help.
