Is this the right id? I couldn't find it in the list archive.

Yes, I wondered about this, too. It seems like at worst the
notmuch-show-process-crypto stuff would be duplicated. This might be
little enough that it's not worth worrying about, or it might be worth
introducing something like
(defun notmuch-with-temp-part-buffer (message-id nth action)
(let ((process-crypto notmuch-show-process-crypto))
(with-temp-buffer
(setq notmuch-show-process-crypto process-crypto)
;; Always acquires the part via `notmuch part', even if it is
;; available in the JSON output.
(insert (notmuch-show-get-bodypart-internal message-id nth))
(funcall action))))
You could also do this as a macro, but that definitely seems like
overkill.
