Same here. However, I have debbugs installed from elp - maybe this makes
a difference. Do you have it installed?

Best regards, Michael.

Yes.  I'll try the current trunk later.

I imagine the issue is with your (stale?) local copy of

   .emacs.d/elpa/archives/gnu/archive-contents

rather than with your version of emacs.

Sounds like

Perhaps.  What should I do?  Delete that file?  Or is there a cleaner way?

I suggest you start by deleting it, yes.

Deleting and regenerating it didn't work.

OK, I'm out of ideas. You'll have to debug why this happens for you.

Hi,

I re-opened the bug because I had it too, and was now able to reproduce
it. The problems lies in
~/.emacs.d/elpa/debbugs-0.6/debbugs-pkg.el

Here's how to reproduce:

NEWHOME=/tmp/a-new-home/
mkdir $NEWHOME
HOME=$NEWHOME emacs -Q --eval '(progn (setq debug-on-error t) 
(package-initialize) (package-refresh-contents) (package-install (quote 
debbugs)) (describe-package (quote debbugs)))'

I hope this helps other to reproduce.

I see this bug.

The problem is that the package description before installing a
package has a quoted list, and after installing it, isn't quoted:

;;; Before installing debbugs

[cl-struct-package-desc
 debbugs
 (0 6)
 "SOAP library to access debbugs servers"
 nil
 tar
 "gnu"
 nil
 ((:keywords quote ("comm" "hypermedia"))
  (:url . "http://elpa.gnu.org/packages/debbugs.html"))
 nil]

;;; After installing debbugs

[cl-struct-package-desc
 debbugs
 (0 6)
 "SOAP library to access debbugs servers"
 nil
 nil
 nil
 "c:/devel/emacs/site-lisp/elpa/debbugs-0.6"
 ((:url . "http://elpa.gnu.org/packages/debbugs.html")
  (:keywords ("comm" "hypermedia")))
 nil]

so package-desc--keywords gets confused.

This one looks incorrect.

OK, but then, why does package-desc--keywords explicitly check for it?
Perhaps hysterical raisins?

(defun package-desc--keywords (pkg-desc)
  (let ((keywords (cdr (assoc :keywords (package-desc-extras pkg-desc)))))
    (if (eq (car-safe keywords) 'quote)
        (nth 1 keywords)
      keywords)))

Also, that's how it is stored in elpa/archives/gnu/archive-contents:

(debbugs .
          [(0 6)

Hmm... that's also an error.
The quote is only needed&useful on the (define-package ... :keywords
'("comm" "hypermedia") ...) form.

It's a hack, kinda. You're welcome to implement it better.

The bug in question, though, should be fixed with revision 116830.

I wasn't complaining about your questions either. You're really welcome 
to rewrite it. :)

While this printed representation isn't something I planned on, the 
structure works as intended, and it should be possible to "unquote" in a 
later Emacs version (http://debbugs.gnu.org/16222#56).
