problem when extracting MIME parts

In my configuration (Gnus v5.13), MIME part extraction does not work,
currently, for a few mail messages (typically X-Mailer: Apple Mail) -
everything as intended for most mail messages, though.

What happens is the following: Upon C-o (gnus-mime-save-part-and-strip)
the MIME part is saved (as expected), but the mail itself gets lost.

A (stripped-down) example of such a mail message is below.

The only "reminder" of the mail message in the nnfolder backend file is:

From nobody Tue Feb 24 22:07:51 2015
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii

and the debugger (only if activated via debug-on-error) shows:

Debugger entered--Lisp error: (error "No such part")
signal(error ("No such part"))
error("No such part")
gnus-article-jump-to-part(0)
gnus-mime-save-part-and-strip()
funcall-interactively(gnus-mime-save-part-and-strip)
call-interactively(gnus-mime-save-part-and-strip nil nil)
command-execute(gnus-mime-save-part-and-strip)

The problem manifests for several weeks now, but I couldn't trace its
origin: change in Gnus, change in my configuration, change in in the
format of (Apple Mail) mail messages.

Any help/hint greatly appreciated.
