Unfortunately the bug is still present:

This time I had opened two separate windows, each running mutt with
the same mailbox open. I was viewing a message in the first mutt,
and composing a reply to another message in the second mutt.

After sending the reply and closing the second mutt (which marked
the message as replied), the first mutt crashed with this notice:

Sorting mailbox...Segmentation fault (core dumped)
