[Dovecot] 1.1b1 initial pop3 login: assertion failed

[David Jonas]

Currently running 1.0.2 with 1.1b1 listening on a different port. On
first pop3 login on 1.1b1 I received an immediate disconnect (I was
testing with telnet) with the log entries below. Subsequent logins work
fine. Other accounts that I tried did not have the same problem. So this
is probably isolated to some bad indexes or something, but I thought I
should let Timo know.

Regards,

David
