I think I have read this document, but in some way, I managed to miss the 
section on the magic file. Just to be sure, it means that only files without 
an extension (or with an unrecognized extension) are scanned to recognize 
their mime type.

The problem is that there is a number of file types which have a generic 
extension, like "iff" or "ogg" for iff files and ogg (vorbis or theora) 
files, which could be bound in general to quite different types of 
applications.

So maybe there should be a way for a mimetype .desktop file to ask for the 
file to be scanned explicitely.
