Looking at https://bugzilla.mozilla.org/attachment.cgi?id=9319413 I suspect the client is handling the wrong response? Client sent the C: 20... but then the late response for authenticate S: 19 OK [CAPAB... which of course doesn't have messages.

I also saw C: 82 ID responses coming in late causing this.
