This looks broken. There's no way it can crash in there. Also it can't
go there directly from io_loop_run(). You sure this core was from imap-
login and not something else?

This is it! This is what was causing the crashes I knew about. And now
I also understand it, it's because username or password contained some
characters that caused Dovecot to send LOGIN command using literals
instead of quoted strings, which in turn sends that "+" line which
Dovecot assumed was a reply to AUTHENTICATE command. This fixes it: http://hg.dovecot.org/dovecot-1.2/rev/8e8a706d6905
Now, if you still get crashes, there's something else broken too.
