        * lib/diagramdata.c app/diagram.c app/disp_callbacks.c
          plug-ins/python/pydia-diagram.c plug-ins/python/pydia-diagramdata.c :
        removed use of chached variable DiagramData::selected_count
        * lib/diagramdata.h : renamed to selected_count_private
        (kept for binary compatibility and sanity checks)
        * lib/diagramdata.c : more checks on a screwed up selection list

        * app/diagram.c(diagram_group_selected) : don't screw up the
        DiagramData::selected list, was assignment of parent_list_affected(),
        * lib/diagramdata.c (data_select, data_unselect) : protect against
        multiple selections of the same object and removement of a not selected
        object (apparently caused by the recently added group undo stuff)
        together with the above this finally fixes bug #153525

        * app/Makefile.am : fix ./autogen.sh ->
        app/Makefile.am:171: blank line following trailing backslash

        * app/commands.c(objects_group_callback,objects_ungroup_callback) :
        ddisplay_do_update_menu_sensitivity() here as well

        * configure.in : make the experimental state of the cairo plug-in
        more visible

        * app/dia-props.c(diagram_properties_update_sensitivity) : don't
        try to update anything if we can't find an active diagram
        Additionally set static dialog pointer to NULL by gtk_widget_destroyed

        * configure.in : another attempt to fix bug #155166. If there is
        anyone with autotools knowledge reading this - help appreciated ;-)
