An error message is being displayed in Emacs's echo area (minibuffer) when the following text is entered into an empty file's buffer while running SLIME:

 (quote (

That is, the error message is displayed after the second left/open parenthesis is typed, before any additional keys such as [Return] or [Space] are pressed.

1. Using CLisp with SLIME, the message is:

   Arglist Error: "The object to be destructured should be a list with at

least 1 elements, not NIL."

2. Using SBCL with SLIME, the message is:

   Arglist Error: "error while parsing arguments to DESTRUCTURING-BIND: .."

Major mode: Lisp Minor mode: ElDoc [COMMON-LISP-USER sbcl] (or clisp)

Note that editing with balanced parentheses does not eliminate this problem. Enter balanced parentheses (for example, using paredit) text in the following order, where | indicates where the cursor is:

Step 1 - Enter parens: (|) Step 2 - Enter "quote ()" inside the parens: (quote (|)) Step 3 - Enter a "+" character inside the inner parentheses: (quote (+|))

After "+" is typed, the error message above is displayed in the echo area.

Emacs was started with the following command:

$ /usr/bin/emacs -nw -Q --load ~/.emacs.d/lisp/minimal-slime-init.el empty.lisp

where the file 'empty.lisp' does not already exist, and the content of 'minimal-slime-init.el' is:

;--- snip ---

;;; M-: (info "(slime)Autoloading") (setq inferior-lisp-program "/usr/bin/clisp") (setq inferior-lisp-program "/usr/bin/sbcl")

(add-to-list 'load-path "~/.emacs.d/lisp/slime")

(require 'slime-autoloads)

(eval-after-load "slime" (slime-setup '(slime-repl slime-autodoc)))

(sleep-for 2) (slime) ;--- snip ---

If '(slime-repl slime-autodoc) is replaced with '(slime-fancy) in the call to `slime-setup', the same error message is displayed.

The following software was used:

1. CLisp 2.47
2. SBCL 1.0.30
3. GNU Emacs 23.1
4. SLIME from CVS, updated on 3 Dec 09 slime.el, revision 1.1254 slime-autoloads.el, revision 1.6 contrib/slime-autodoc.el, revision 1.24 contrib/slime-fancy.el, revision 1.9 contrib/slime-repl.el, revision 1.33

Thanks for the very detailed bug report (though the information i actually used was in the first paragraph). Fixed in CVS.
