Yes, I can replicate this bug in emacs 25.1 by

1) ./devel/try-emacs-mua -q

2) (setq notmuch-mua-compose-in 'new-frame)

3) reply to an html only message.


If I M-x toggle-debug-on-error I get a backtrace ending in

set-window-buffer(nil #<buffer  *temp*-321945>)
shr-pixel-column
shr-string-pixe-width
shr-insert-document
notmuch-show--insert-part-text/html-shr

I can't find an html only public-message so far to give a full
backtrace.
