Start Emacs as an OS X GUI app.  Then, evaluate

    (global-set-key (kbd "s-i") #'foo)

where `foo' is undefined.
Then, press C-h k s-i.  The help buffer explains:

    s-i runs the command foo (found in global-map), which is an alias
    for `foo', which is not defined.  Please make a bug report.

To solve this "bug", don't bind a key to a function that is undefined.
