Btw, the code which injects this nil into the frame parameters is no
other than oneonone.el itself.  It has this part:

    (defcustom 1on1-minibuffer-frame-alist
      (list
       (or (assq 'foreground-color minibuffer-frame-alist)
           (cons 'foreground-color 1on1-minibuffer-frame-foreground))
       [...]
       (or (assq 'menu-bar-lines minibuffer-frame-alist)
           (cons 'menu-bar-lines nil))
            ^^^^^^^^^^^^^^^^^^^^^^^^^

If I replace this with `(cons 'menu-bar-lines 0)', the original
problem goes away without any changes in menu-bar.el.

Drew, any reason not to make that change in your package?
