I think it'd be better as 0 to mean sort of no format at all,

        * gdk-support.c (gdk_selection_property_get_interp): Tweak to
        initialize prop_type and prop_format unconditionally, so as not to
        depend on gdk_selection_property_get at all for this.  Use 0 for
        prop_format not given by gdk_selection_property_get.
