Actually, Non-GNOME systems won't be covered with --enable-gio, because the gio service is in the mozgnome component, which depends on GNOME libs, which will most likely fail to load on non-GNOME systems. And if mozgnome loads anyway, it contains the GnomeVFSService, which would already use gnome_vfs_mime_application_launch. So --enable-gio would change nothing.
