that code is python.  here it is, but i don't think it's the problem
(see next bit below):

def return_addresslist (queryterm, predicate, buff):
    results = abook.search(queryterm)
    names =[]
    for record in results:
        name = record.get_name()
        address = record.get_property('email_1')
        names.append(name + " " + "<" + address +">")
        for i in ["2","3"]:
            if record.get_property('email_' + i):
                 address = record.get_property('email_' + i)
                 record.get_property('email_' + i)
                 names.append(name + ' '+ "<" + address +">")
    return names

it just returns a list of strings, which is what i thought
completing-read wanted to receive.

i think ad-Orig-minibuffer-complete comes from the
minibuffer-complete-cycle package; i've taken out references to it in
my .emacs for now.  but my issue persists.

i think this came from minibuffer-complete-cycle.

um, i'm sure i just don't know what i'm talking about...

or in my understanding of completing-read, see below.

hmm, i thought i wanted edsquery to give a list of strings.  i have the
following trivial code which is still giving the same kind of error, and
i think probably illustrates my conceptual error, whatever it is:

( matt/external-addressbook-completion (stub)
"get a list of addresses for tab-completion in a new email"
  (interactive (list (completing-read "Name: "
      #'static-list
;;       collection
      nil t))))

(defun static-list (s p n)
  '("matt1" "matt2" "matt3"))

(setq collection '("matt1" "matt2" "matt3"))

if i let 'collection' serve as the collection, the function works as
expected; but if 'static list' is called instead, i once again have a
type error:  
minibuffer-complete: Wrong type argument: number-or-marker-p, ("matt2"
"matt3")
my confusion, i guess, is that I'd thought the two should evaluate to
the same list '("matt1" "matt2" "matt3").  clearly i'm misunderstanding
something but it's the kind of conceptual error i have trouble finding
an answer for in the documentation.

thanks again.  you should feel free to drop me, though, drew -- i
appreciate all your efforts.
