Getting menu to show

[Jonathan Hayward <christos jonathan hayward gmail com>]

I'm trying to get a menu bar to show. The code I have at present is segfaulting:

void gtk_specific_init(int *argc, char ***argv)
    {
    GtkItemFactory *factory;
    gtk_init(argc, argv);
    main_window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_widget_show(main_window);
    gtk_accelerators = gtk_accel_group_new();
    factory = gtk_item_factory_new(GTK_TYPE_MENU_BAR, "<main>",
      gtk_accelerators);
    gtk_item_factory_create_items(factory, 125, menu_entries, NULL);
    gtk_window_add_accel_group(main_window, gtk_accelerators);
    /*
    gtk_check_menu_item_set_active(GTK_TYPE_MENU_BAR
      (gtk_item_factory_get_item(factory, "<main>")), TRUE);
    */
    gtk_widget_show(gtk_item_factory_get_item(factory, "<main>"));
    };

I suspect that there's a problem with the last call, and I'd like to be told what I should do instead to get menus to display.

The source file reads (did I handle the submenu at "/Movement/Alternate
and Expanded" correctly by declaring it to be of type
"<Branch>")?:
