After upgrading to 12.10 I discovered that Gnome-Sushi no longer allows you to play MP3's. If you press the spacebar a window opens but that's all that happens. All codecs are installed and I can play MP3's with Rhythmbox etc.

This is actually a big deal as when I upgraded to 12.04 the really nice feature whereby one hovered the mouse over a nautilus MP3 file and it played was removed and we had to use Sushi. Now Sushi is broke and there is no way to preview MP3's anymore.

I hope there is a fix or workaround because I really need an MP3 preview.
