I'm scrwed now as well. I had next theme widgets that won't go away and i tried the new aquafix and it hosed duality leaving me with a permanent KDE theme. I can't get aqua back because duality just freezes now. So I have to use a KDE theme with next widgets and icons 
Anyone know what files need to be replaced and their location to get aqua back?
