Hi,
I've noticed a problem when replying to an encrypted email when I have
html set as preferred over plain text. Looks like notmuch fails to parse
the body and the original body text in notmuch-reply just looks like this:

> [ text/html ]
> !!! Bodypart insert error: End of file during parsing !!!

A few things which might help understand what could be happening here...

notmuch from git with head @ 07b6220
gmime 2.6.20-r1 (gentoo)

(setq mm-text-html-renderer 'shr)
(setq shr-inhibit-images nil)
(setq mime-view-text/html-previewer 'shr)
(setq mm-inline-text-html-with-images t)

(set-locale-environment "en_GB.UTF-8")
(set-language-environment 'utf-8)
(set-selection-coding-system 'utf-8)
(prefer-coding-system 'utf-8)
(set-default-coding-systems 'utf-8)
(set-terminal-coding-system 'utf-8)
(set-keyboard-coding-system 'utf-8)
(setq default-buffer-file-coding-system 'utf-8)

(setq notmuch-multipart/alternative-discouraged '("text/plain"
"multipart/related"))

The message I'm replying to looks like:

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:38.0) Gecko/20100101

Notmuch shows this as:

[ multipart/encrypted ]
[ Decryption successful ]
[ Good signature by:  xxxx ]
[ application/pgp-encrypted ]
Version: 1
[ multipart/mixed ]
[ multipart/alternative ]
[ text/plain (hidden) ]
[ multipart/related ]
[ text/html (hidden) ]
[ image.jpg: image/jpeg (hidden) ]

Things of interest:

1/ I have the same encrypted email in plain text only and replying to it
works fine with notmuch.

2/ I can view the html from the email in a browser, and it looks fine.

3/ If I switch emacs to use w3m instead of shr, I don't see the 'Bodypart
insert error' fro notmuch-reply but there is no original message included
in the reply composition either.

I'm not quite sure if this is a notmuch issue as such, or attributed to my
emacs config, or something else...

I don't know exactly what is supposed to happen when replying to html
emails, but if I reply to an html email which is not encrypted, there is
no '> [ text/html ]' in the reply composition window - it's just text from
the original message that I'm replying to and nothing more.

Since the encrypted email I'm replying has a text part, can notmuch use
this and quote it when replying (obviously ensuring that the entire reply
will be encrypted).

Any thoughts?

Thanks a lot.
