bug#16166: 24.3.50; can't use news.gmane.org with gnus and gnutls since r115532

[Nicolas Richard]

hello,

Recipe:
./emacs -Q --batch --eval '(setq gnus-select-method (quote (nntp "news.gmane.org")))' --eval '(gnus)'

Result:
>>> (wrong-type-argument listp nil)
nntp (news.gmane.org) open error: '>>> (wrong-type-argument listp nil)'.  Continue? (y or n)

Additionnaly, it took me some time to figure out how to obtain a
backtrace, but it worked by evaluting these from -Q:

;; first try opening gnus, to autoload stuff
(let ((gnus-select-method '(nntp "news.gmane.org")))
  (gnus nil t))
;; then get the backtrace
(let ((gnus-opened-servers) ; forget that it just failed
      (debug-on-signal t)) ; force entering debugger
  (gnus-open-server (list 'nntp "news.gmane.org")))

the backtrace then is (byte code contains NUL, which will be stripped
when I send this message):

Debugger entered--Lisp error: (wrong-type-argument listp nil)

the "problem" is that :verify-error is nil.

This is a duplicate of #16161

I didn't hit "Retrieve new messages" often enough, sorryf or the noise.
