I use notmuch with Emacs, and it looks like the latest package there has
broken my sending functionality. 

When pressing C-c C-c (notmuch-mua-send-and-exit) in a message buffer,
for some reason eww gets called with a http://mailto:// link, followed
by the body of the message. 

I'm not sure at all why this is the case -- I haven't changed my notmuch
or Emacs config, and I use msmtp, not eww, to send mail. 

I'd be happy to provide those configs if that's useful.
