Hi, I switched to trying emacs 25 (25.1) with notmuch the other day. I really like some of the improvements that have been made (in particular, SHR seems to do a much nicer and quicker job of rendering html emails). However, things came a little unstuck when I tried to reply to an email with notmuch. I have notmuch set to discourage plain text simply because I deal with a lot of email which is sent in html (people frequently in-line tables, images etc) and when I replied, notmuch generated the following in the new message buffer: > !!! Bodypart handler `notmuch-show-insert-part-text/html' threw an error: > !!! Window is dedicated to ‘*unsent mail to user@domain.com*’ > Errors like these are generated by replying from either notmuch-tree or notmuch-show. I'd made no changes to my .emacs before switching to 25 and just to check, I switched back to 24 (24.5) and I could reply to the same email without any trouble. I'm of the opinion that this is probably some sort of set up / configuration issue specific to 25, but I'm quite surprised. I don't have many settings for handling html stuff: (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) (setq notmuch-multipart/alternative-discouraged '("text/plain")) Is this reproducible for anyone else with notmuch from git/master as of today?
