for the emission of AFTER signals, fetch the objects signals via

Browse Source 
Tue Feb  3 15:09:55 1998  Tim Janik  <timj@gimp.org>

        * gtk/gtksignal.c (gtk_signal_real_emit): for the emission
          of AFTER signals, fetch the objects signals via
          gtk_signal_get_handlers again. some handlers might have
          been removed or added. not doing this would mess up the
          memchunk allocation of signal handlers (this had been
          triggered by multiple *_while_alive connections), bad, bad, bad!
          (gtk_handlers_run): do the referencing on signal handlers
          unconditionally, the invokation of AFTER handlers will now take
          care of modified lists.

        * gtk/gtksignal.h: added gtk_signal_connect_while_alive.
