<pre wrap=""> I will commence with trying to figure out what is causing the problem. I've seen some weirdness with margins when viewing HTML messages too. Maybe that's some kind of bizarre toolkit thing... Anyway, thanks a lot for testing and for confirming that there's no problem. </pre>

<pre wrap=""> 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. </pre>
