Using amarok to play music from collection in random playlist mode.
In the middle of the current song (song: A), I pressed 'next song' on the
gui.  The next song, (song: B) started to play.  I then decided to play
the previous song (A) again.  Amarok stopped playing music, and displayed
the 'Welcome to Amarok' message in the song title description.

I brought up the play list to select song A again, and pressed play.
Song A was added to the playlist after song B, and amarok did not start
playing.  I repeated the action, and song A again was added to the
playlist, again after song B.  

After pressing play again on the playlist UI, the UI begin to fill with
an unrecognized song, neither song A nor song B.

I quit amarok and restarted.  The playlist restored to its state prior to
the error. 

These messages were displayed from where amarok was started from that
are not part of the usual messages that amarok displays at startup.
They may have something to do with the observed behaviour:
QObject::disconnect: Unexpected null parameter
QObject::connect: Cannot connect (null)::activePartChanged( KParts::Part * ) to KHTMLPart::slotActiveFrameChanged( KParts::Part * )
