        * gtk/gtkmain.c (gtk_propagate_event): fixed a bad, bad referencing
          bug that could caused unreferencing of finalized objects.

        * gtk/testgtk.c: destroy fileselection on "OK" (this triggered the
          above mentioned bug).

        * gtk/gtkwidget.h:
        * gtk/gtkwidget.c:
        * gtk/gtkobject.h:
        * gtk/gtkobject.c:
          implemented and object reference tracer (gtk_trace_referencing) which
          is activated if GTK_TRACE_OBJECTS is defined (currently per default).
          in gdb: set the static variable `gtk_trace_object' to point to the
          object that you want to have reference traced.

        * gtk/gtkfileselection.c: few cleanups.
