bug#16873: 24.3.50; `describe-package' error: (wrong-type-argument char-or-string-p ("comm" "hypermedia"))

[Juanma Barranquero]

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.
