[Pkg-mutt-maintainers] Bug#884324: segfault with `neomutt -a $file'

[Sebastian Andrzej Siewior]

Source: neomutt
Version: 20171208+dfsg.1-1
Severity: Important

I tried
	neomutt -a $file
it then prompts for To:, Subject: and opens $EDITOR. After that I tell
it send. Neomutt saves the email in the `Sent' folder and crashes then:
