        * gtk/gtkobject.c: remove quark_user_data usage in
        gtk_object_{g|s}et_user_data(). fixes get_user_data()
        returning NULL for user_data set through property interface.

        * gtk/gtkitemfactory.c (gtk_item_factory_create_item): don't put out
        warnings if a pixbuf couldn't be retrieved, since (a) this doesn't
        need to be a programming error (in case of loaded data), (b) it breaks
        with 2.0 behaviour where extra magic could be used to create empty
        images. don't attempt to retrieve pixbufs from NULL extra_data.
