C-x d RET              ;; with truly distinct names
M-`                    ;; menu-bar
b                      ;;   buffers
f                      ;;     frames
0                      ;;       (The current frame, perhaps not labelled
                       ;;        with 0)

causes

menu-bar-select-frame: Wrong type argument: framep, nil

The following seems to work as a patch

*** /ld1/local/share/emacs/21.3/lisp/menu-bar.el        Tue Apr 23 08:13:16 2002
--- /tmp/menu-bar.el    Tue Feb  8 12:46:03 2005
***************
*** 1008,1017 ****
--- 1008,1018 ----
    (interactive)
    (let (frame)
      (dolist (f (frame-list))
        (when (equal last-command-event (frame-parameter f 'name))
        (setq frame f)))
+   (setq frame (or frame (selected-frame)))
    (make-frame-visible frame)
    (raise-frame frame)
    (select-frame frame)))

  (defun menu-bar-update-buffers-1 (elt)

Yes, selecting the current frame is a little silly, but it shouldn't cause
a lisp-y error message.

Yours sincerely,
David
