That's  a  strange  behaviour.  Here  is  an  example which shows that
the   "destroy"   signal   is   sent  to  the  GtkMenuItem  when  you
gtk_widget_destroy it:

# include <gtk/gtk.h>

void warn (GtkWidget *);

int
main (int argc, char **argv)
{
  GtkWidget *win, *menubar, *file;

  gtk_init (&argc, &argv);
  win = gtk_window_new (GTK_WINDOW_TOPLEVEL);


  menubar = gtk_menu_bar_new ();
  file = gtk_menu_item_new_with_label ("File");
  gtk_signal_connect (GTK_OBJECT (file),
                      "destroy",
                      GTK_SIGNAL_FUNC (warn),
                      NULL);

  gtk_signal_connect_object (GTK_OBJECT (win),
                             "delete_event",
                             GTK_SIGNAL_FUNC (gtk_widget_destroy),
                             GTK_OBJECT (file));

  gtk_container_add (GTK_CONTAINER (menubar), file);
  gtk_container_add (GTK_CONTAINER (win), menubar);
  gtk_widget_show (win);
  gtk_widget_show (menubar);
  gtk_widget_show (file);
  gtk_main ();
}
void
warn (GtkWidget *wid)
{
    g_print ("\n\n reached \n\n");
}

When  you  execute  it,  and  delete  the window (sending by the way a
delete_event),  the  warn  function is run and "reached" is shown. So,
there's probably an error in your code.

lfan> Is there anything different from how the "destroy" signal is sent to a
lfan> signal handler function for a GtkMenuItem than a GtkCombo?

When  destroying  a  widget,  Gtk+ don't care about it's a GtkCombo or
GtkMenuItem. It sends a destroy signal, and that's all.
