Running Dovecot-1.1.5, I see this assertion failure:
Panic: pop3-login: file sasl-server.c: line 75
(authenticate_callback): assertion failed: (client->auth_request ==

This happens when I feed multiple user/pass lines to Dovecot all at
once like this:
$ telnet gromit 110
Connected.
Escape character is '^]'.
+OK Dovecot ready.
user x
pass y
user x
pass y
+OK
+OK
Connection closed by foreign host.
The four user/pass lines I pasted in all at once.
IMAP login does not crash when presented with multiple login commands,
but it does not read them all at once and needs prodding (in the form
of extra command lines sent later on) to read them. Actually it
appears to read the first two lines then stops reading until more data
comes in:
$ telnet gromit 143
Connected.
Escape character is '^]'.
* OK Dovecot ready.
a login a b
b login c d
c login e f
d login g h
e login i j
a NO Authentication failed.
b NO Authentication failed.
c NO Authentication failed.
d NO Authentication failed.
e NO Authentication failed.

You probably don't care about the odd imap-login behavior, but I tried
it and mentioned it just for completeness after seeing pop3-login crash.
