So how does nautilus identify it's mime type?  It does not seem to use 
'file' as I can modify /usr/share/file/magic and run file -C 
/usr/share/file/magic and nautilus still comes up with RIFF audio. 
Where is gnome/nautilus's magic kept?

To be honest, I've never had a clear understanding of the whole file 
extension/file type/mime type scheme.  I always get the impression that 
the whole concept is kind of broken.

Thanks,
Steve
