Subject: 24.5; Error with directory local variables
Date: Thu, 14 Apr 2016 14:48:50 -0500

I downloaded log4cplus from SourceForge. In it's top level directory is
the file .dir-locals.el with the following contents:
;;; Directory Local Variables
;;; See Info node `(emacs) Directory Variables' for more information.

((nil .
  ((fill-column . 79)
   (indent-tabs-mode)
   (show-trailing-whitespace . t)
   (whitespace-style face trailing lines-tail space-before-tab indentation empty)
   (whitespace-newline . t)))
 (c++-mode .
  ((tab-width . 4)
   (whitespace-action warn-read-only auto-cleanup)))
 (cmake-mode .
  ((whitespace-action warn-read-only auto-cleanup))))

When I try to navigate to that directory with dired I get prompted for
y,n or !. Both y and n yeild the same results:
hack-local-variables-confirm: Wrong number of arguments: #[nil "À ?†.Á ƒ.Âp!‡Ã ‡" [menu-bar-menu-frame-live-and-visible-p menu-bar-non-minibuffer-window-p kill-buffer abort-recursive-edit] 2 2382972 nil], 1

When I set debug-on-error I get this stack trace:

FWIW I can't reproduce this. Does it happen with emacs -Q?
(I note you have some XEmacs packages shadowing standard Emacs libraries.
Not obviously related though.)

I do not see the problem with
/Applications/MacPorts/Emacs.app/Contents/MacOS/Emacs -Q

I assume that means it's something with my packages. I wasn't aware of
any of my xemacs packages shadowed any standard Emacs libraries. What's
the best way to find those?

Yep.

It's in your original report. Or you can use M-x list-load-path-shadows.
That may not be the actual problem.
It may help to M-x debug-on-error and repeat the problem.

Replacing this:
(unless (boundp 'quit-window)
  (defalias 'quit-window 'kill-this-buffer))

with:
(unless (or (fboundp 'quit-window) (boundp 'quit-window))
  (defalias 'quit-window 'kill-this-buffer))

fixed it.
