Two are better than one! (I have no idea why.)

I've expected that.

What an appropriately named function that is. ;-) No, that wouldn't
help. But its code could be stolen to write and own function to insert
the right NOV file in a temp buffer, to search for the message-id.
Something like that:
--8<---------------cut here---------------start------------->8---
(defun org-gnus-nnimap-get-article-number (group server message-id)
(with-current-buffer nntp-server-buffer
(let ((nov (nnimap-group-overview-filename group server)))
(when (file-exists-p nov)
(mm-insert-file-contents nov)
(set-buffer-modified-p nil)
(when (search-forward message-id nil t)
(goto-char (line-beginning-position))
(read (current-buffer)))))))
--8<---------------cut here---------------end--------------->8---
That function is totally untested, but might do what it should.

Really strange. Maybe the corruption comes from replacing TABs by
spaces using some home-brewn auto-replace-all-tabs-with-spaces function?
