... weird... I happen to have multiple entries for files with a pdf 
extension.  One of them says "application/x-pdf", onother one 
"application/binary" and another one "application/octetstream".

So our problem might be the consequence of the usage of older firefox 
version that for some reasons wrote wrong things (or things in the wrong 
order) in the file.

I believe that we need to find out if a clean profile autogenerated by 
the latest firefox shipped with Ubuntu creates the correct entry for pdf 
If it does, then we do not have a bug with ubuntu's latest firefox.  We 
have just something to put in the wishlist: namely a way to manage the 
mimetype file when something goes wrong.

Conversely, if a clean profile autogenerated by the latest firefox 
shipped with Ubuntu creates an uncorrect entry for pdf files (binary, 
octetstream), then we have a bug.
