currently, if totem comes accross a non-multimedia file in its playlist,
a big error box pops up and totem stops playing altogether.  it should
gracefully bypass that file and move to the next one without stopping
playback.

a resonable way to do this would be to use the notification area to
present a popup briefly describing what happened, but please continue on
to the next track in the list.

thanks for the hard work.
