I don't see it - could you send me a sample Emacs Lisp file where it
fails for you, just to ensure we're on the same page?
As far as I can tell the problem happens for all emacs-lisp files
including empty emacs-lisp files.
xemacs -vanilla (21.4.18)
eval the defun and add-hook in the new vanilla xemacs and open the
empty emacs-lisp file:
C-x C-f fubar.el
M-x == 'Wrong type argument: stringp, nil'
I stepped through outline-minor-mode. The problem comes from this
hook added to change-major-mode-hook:
(function (lambda nil (outline-minor-mode -1)))
This code turns M-x into 'Wrong type argument: stringp, nil' I
don't know anything about this hook and what it has to do with M-x.
Maybe it does something to the minibuffer, since any command that
uses the minibuffer to prompt gets the error. Anyway, evaling
makes the problem stop.
Moreover, could you try this with 21.5?
21.5 was pretty bad the last time I tried it. I've pretty much
forgotten the details so maybe I'm ready to try 21.5 again at some point.
It won't be anytime soon.
