        * gtk/gtksignal.c (gtk_handlers_run) (gtk_signal_real_emit):
        sropped the approach of copying all signal specific data into a
        GtkHandlerInfo structure. we rather keep the signal data on the stack
        in gtk_signal_real_emit and pass that over to gtk_handlers_run. this
        avoids multiple lookups of the signal pointer and works savely together
        with destroy notifiers of handlers.

        * gtk/gtkentry.c (gtk_entry_key_press): care for the posssibility that
        someone destroys the entry on the ::activate signal.
