[NoGnus] Fancy splitting and imap respooling not working

[Sebastien Vauban]

Hi,

I've just switched to NoGnus v0.18 (pull of yesterday) with lots of delight.
Performance are much better.

The only problem I have: the fancy splitting (via BBDB) is not working
anymore. All the mails arrive in my INBOX, unlike what I ask for:

#+begin_src emacs-lisp
      ;; the registry should be installed
      (setq gnus-registry-install t) ;; for `G G' searches

      ;; the first match in `nnimap-split-rule' found will be used
      (setq nnimap-split-crosspost nil)

      ;; name(s) of IMAP mailboxes to split mail from
      (setq nnimap-split-inbox '("INBOX"))

      ;; BBDB (Big Brother DataBase) is loaded from my `.emacs' file
      (when (try-require 'bbdb-gnus)

        ;; split function to use (sorting mails into groups using BBDB)
        (setq nnimap-split-rule 'bbdb/gnus-split-method)

        ;; fallback if the BBDB doesn't specify a group
        (setq bbdb/gnus-split-nomatch-function 'nnimap-split-fancy))

      ;; specify how to split mail
      (setq nnimap-split-fancy
            ;; split to the first rule making a match
            `(|
              (from mail "INBOX.errors")

              ;; catch spam
              ("X-Spam-Status" "[Yy]es"
               "INBOX.Spam")

              ;; people, mailing lists, etc.
              ("To" "info@other\\.com" "INBOX.other")
              ("Subject" "\[O\]" "INBOX.org-mode")

              ;; unmatched mail goes to the catch-all group (default mailbox)
              "INBOX"
              ))
#+end_src

A couple of minutes ago, when trying to respool one of those emails (which
landed in INBOX), I got this error:

--8<---------------cut here---------------start------------->8---
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
  encode-coding-string(nil utf-7-imap)
  utf7-encode(nil t)

  gnus-request-accept-article(nil (nnimap "mc" (nnimap-address 
"mail.company.com") (nnimap-authenticator login)) t t)
  eval((gnus-request-accept-article nil (quote (nnimap "mc" ... ...)) t t))
  nnimap-request-move-article(24944 "INBOX" "mc" (gnus-request-accept-article

  gnus-request-move-article(24944 "nnimap+mc:INBOX" "mc"

  gnus-summary-move-article(nil nil (nnimap "mc" (nnimap-address 
"mail.company.com") (nnimap-authenticator login)))
  gnus-summary-respool-article(nil (nnimap "mc" (nnimap-address 
"mail.company.com") (nnimap-authenticator login)))
  call-interactively(gnus-summary-respool-article nil nil)
--8<---------------cut here---------------end--------------->8---

Now, after a restart (and maybe a switch between Emacs 23 and 24), I also have:

--8<---------------cut here---------------start------------->8---
Unable to contact mail.company.com:nil via ssl
Couldn't Move article 24956: Unable to contact mail.company.com:nil via ssl
--8<---------------cut here---------------end--------------->8---

Can you help?

Best regards,
  Seb
