The Help menu break in bonobo-browser program of libbonoboui package. It give followning message in the console: (bonobo-browser:28286): Bonobo-WARNING **: Unknown stock id 'gnome-stock-about' on /menu/Help/HelpAbout And when I look into it source code, I find this. static void verb_HelpAbout (BonoboUIComponent *uic, void *data, const char *path) { static const gchar *authors[] = { "Dan Siemon <dan@coverfire.com>", "Rodrigo Moya <rodrigo@gnome-db.org>", "Patanjali Somayaji <patanjali@morelinux.com>", NULL }; #if 0 GtkWidget *about; about = gnome_about_new (_("Bonobo Browser"), VERSION, _("Copyright 2001, The GNOME Foundation"), _("Bonobo component browser"), authors, NULL, NULL, NULL); gtk_widget_show (about); #endif } I don't know why the About menu item was comment out use #if 0. If they don't want the About menu to shown, just remove it completely, or let it perform normally as it should (remove the #if and #endif).
I guess it got disabled because it's deprecated API. bonobo-browser is a developer tool and I don't think there's much care for the UI. The .desktop in 2.14 hides it, so thats sufficient to me. If you want this to be fixed, create a patch and file a bug upstream.
