I got a bit further by usingthe info found in
http://dovecot.org/list/dovecot/2012-September/138334.html

Now I'm getting:
# telnet localhost 143
Trying ::1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE STARTTLS AUTH=PLAIN AUTH=LOGIN] Dovecot (Ubuntu) ready.
. LOGIN hildeb WRONGPASSWORD
. NO [AUTHENTICATIONFAILED] Authentication failed.
. LOGIN hildeb CORRECTPASSWORD
* BYE Internal error occurred. Refer to server log for more information.
Connection closed by foreign host.

The log says:
