Do you mean the selected frame changes in between?

Anyway, I think there are at least three other bugs:

(1) Evaluating Lisp code in `define-key' can crash Emacs.

(2) The menu-bar define-key operations to toggle `menu-bar-mode' and
    `tool-bar-mode' do not take into account that the values of the
    respective frame parameter can be nil.

(3) Frame parameters of `menu-bar-lines' and actual appearance of a
    menubar are inconsistent for minibuffer-only frames.
