A relatively infrequent issue, but a bug nonetheless:
I received a message with an empty subject line.
When I try to reply, reply-all, or forward the message, nothing happens.

Reply & reply-all don’t work, but forward does.
I just came across this same issue with a ‘blank’ To field in the received email (as would happen if I were BCC’d on a message). Cannot reply, reply-all, or forward.

Reproduced issue with replying to message with empty subject line. Added to https://github.com/runbox/runbox7/issues/43.
Not able to reproduce issue with replying to BCC’ed email.
