;; Where PART1 is the html part and PART2 is the pdf part.
If it is (narrow-to-region beg (point)) in gnus-mime-display-single
to issue (args-out-of-range 4409 4410), I guess an html rendering
function deletes buffer's contents so that the buffer's end point
may be 4409. Here is a model to reproduce the same error:
(with-temp-buffer ;; article buffer
(insert-char ?x 4409)
(let ((beg (point))) ;; buffer's end point == 4410
(delete-char -1) ;; html function does this
(narrow-to-region beg (point))))
=> (args-out-of-range 4409 4410)
The default html function is mm-shr, that gnus-mime-display-single
calls by way of mm-display-part, mm-display-inline, and
mm-inline-text-html. At that time, the point is positioned at
the end of the article buffer, where the header lines and a
single empty line are there.

Thanks. However, I couldn't reproduce the error with the mail
that I copied to my nnml group. I tried it using Emacs 26.1
with no ~/.emacs, no ~/.gnus.el, but ~/.newsrc.eld,
(setq gnus-select-method '(nnnil)), and every candidate for
mm-text-html-renderer. The only thing that reproduces it is:
(defadvice mm-shr (before delete-ceiling-newlines activate)
"Delete newlines before the point."
(skip-chars-backward "\n")
(delete-region (point) (point-max)))
Well, if you have time for analyzing the problem, don't you try
edebug on the functions listed above?
Regards,
