gcmd relies on mime info heavily, so this is a must. Obviously, the
problem is caused by GnomeVFS, but as it is deprecated it is hard to get
it fixed mainstream... 

IMO the best solution is to provide an option defining the method of
retrieving mime info: GNOME_VFS_FILE_INFO_GET_MIME_TYPE (standard way)
or GNOME_VFS_FILE_INFO_FORCE_FAST_MIME_TYPE (based on file extensions
only). As the problem seems to be very exotic for 'standard' user, I'd
default it to GNOME_VFS_FILE_INFO_GET_MIME_TYPE

What about it?
