        * gtk/gtktreemodelsort.c (gtk_tree_model_sort_row_deleted): emit
        row_deleted before we start unreffing the nodes ourselves
        (gtk_tree_model_sort_increment_stamp): always increment the stamp,
        and not only if the stamp equals 0 (pointed out by Darin Adler)

        * gtk/gtktreemodel.c (gtk_tree_row_ref_deleted_callback): we want
        to continue the while loop and not the nested for loop.
