This is probably the best solution.

they get stored and processed as if there was no difference [2] (but there's
a difference). What happens later is that g_content_type_is_a will assumes
that it's arguments are not mime-types under windows. In the case of
Gtk2::FileFilter this results in no matches under windows as
g_content_type_is_a is expecting extensions and gets mime-types which don't
match. At the end this is not too intuitive as the documentation of
gtk_file_chooser_add_mime_type doesn't warn us about this behaviour.
