        * gtk/gtksignal.c (gtk_signal_real_emit): pass only the signal_id
        to this function. it needs to relookup the signal multiple times.
        this fixes spurious segfaults that could show up with signal intensive
        code, when classes are created during a pending emission (which is
        normal case).
