Could you send me an article demonstrating the problem?

I'm not familiar with the IMAP code, but AFAICS, `nnimap-demule' is
only used when getting headers or body:
| nnimap.el:611: headers (nnimap-demule
(defun nnimap-retrieve-headers-progress ()
"Hook to insert NOV line for current article into `nntp-server-buffer'."
| nnimap.el:951: (nnimap-demule
(defun nnimap-callback (article gnus-callback buffer)
(when (eq article (imap-current-message))
(remove-hook 'imap-fetch-data-hook
(nnimap-make-callback article gnus-callback buffer))
(with-current-buffer buffer
(insert
(with-current-buffer nnimap-server-buffer
(nnimap-demule
(if (imap-capability 'IMAP4rev1)
;; xxx don't just use car? alist doesn't contain
;; anything else now, but it might...
(nth 2 (car (imap-message-get article 'BODYDETAIL)))
(imap-message-get article 'RFC822)))))
(nnheader-ms-strip-cr)
(funcall gnus-callback t))))
| nnimap.el:977: (insert (nnimap-demule (if detail
(defun nnimap-request-article-part (article part prop &optional
group server to-buffer detail)
Bye, Reiner.
