This is easy to reproduce on linux with thunderbird (I'm using v38.5.0).
Edit -> Account Settings -> Composition & Addressing and check 'Compose
messages in HTML format' and send yourself a pgp encrypted email using
PGP/MIME, open it in notmuch-emacs and reply to it. You'll see the
'Bodypart insert error'.

If you need any more info let me know...
