Yep. From the MIME type you can get to a textual description of the type
(translated for the user's language), a themed icon (using the
freedesktop.org icon theme spec) and even a list of file extensions for
that type (to change the type as you type, if that's what you want).

Also using the shared MIME database and the icon theme spec, assuming we
don't want a GNOME dependency for GTK:

- http://www.freedesktop.org/standards/shared-mime-info-spec
- http://www.freedesktop.org/Standards/icon-theme-spec

(scroll right to the bottom of the first link to find the mapping from
MIME names to icon names)
