1. Launch Gnus dev => no connection to company mail server (imap), well to
   newsgroups... this is the described situation

2. Quit Gnus

3. Eval the above sexpr, resulting in:

--8<---------------cut here---------------start------------->8---
Mark set [2 times]
Opening connection to via tls...
Opening TLS connection to `'...
Opening TLS connection with `gnutls-cli --insecure -p imaps'...failed
Opening TLS connection with `gnutls-cli --insecure -p imaps 
--protocols ssl3'...failed
Opening TLS connection with `openssl s_client -connect 
-no_ssl2 -ign_eof'...failed
Opening TLS connection to `'...failed
Error: wrong-number-of-arguments; Data: (nil 0)
Mark set [2 times]
--8<---------------cut here---------------end--------------->8---

4. Activate debugs:

--8<---------------cut here---------------start------------->8---
   (setq debug-on-error t
         debug-on-signal t
         debug-on-quit t)
--8<---------------cut here---------------end--------------->8---

5. Eval the above sexpr, resulting in backtrace:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-number-of-arguments nil 0)
  signal(wrong-number-of-arguments (nil 0))
  open-protocol-stream("*nnimap*" #<buffer *nnimap nil

  nnimap-open-connection-1(#<killed buffer>)
  nnimap-open-connection(#<killed buffer>)
  eval((nnimap-open-server ""))
  (cond ((and eval-expr-honor-debug-on-error debug-on-error) (eval 
ee::expression)) (t (condition-case ee::err-data ... ...)))
  (let* ((ee::error nil) (ee::result ...)) (cond (ee::error ... ...) 
(ee::insert-value ...) (t ... ...)) ee::result)
  eval-expression((nnimap-open-server "") nil)
  call-interactively(eval-expression nil nil)
--8<---------------cut here---------------end--------------->8---

Is there food for you?
