[Dovecot] Some trouble with dovecot 2.1 and SASL

Hi,

I'm testing dovecot 2.1.0, on Debian 6.0, with "passdb driver = imap" 
and SASL for postfix's SMTP-Auth, like explained ih this howto: 
http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL

Authentications over IMAP (local dovecot -> remote dovecot) works fine, 
and it's great. Also smtp-auth on postfix (over SASL) works fine. But in 
the dovecot log I found this error:


Feb 19 11:11:42 demo-vpop dovecot: auth: Fatal: master: service(auth): 
child 30506 killed with signal 11 (core dumps disabled)

even though all works fine.

This is my dovecot configuration:

# 2.1.0: dovecot.conf-imapc
# OS: Linux 2.6.32-5-amd64 x86_64 Debian 6.0.4
auth_mechanisms = plain login
default_login_user = nobody
imapc_host = 10.0.0.1
mail_gid = imapproxy
mail_home = /home/imapproxy/%u
mail_location = imapc:~/imapc
mail_uid = imapproxy
passdb {
   args = host=10.0.0.1
   default_fields = userdb_imapc_user=%u userdb_imapc_password=%w
   driver = imap
}
protocols = imap
service auth {
   unix_listener /var/spool/postfix/private/auth {
     group = postfix
     mode = 0660
     user = postfix
   }
}
ssl = no
userdb {
   driver = prefetch
}

But if instead of "unix_listener /var/spool/postfix/private/auth" I 
use:

service auth {
   unix_listener auth-userdb {
   }
   inet_listener {
     port = 12345
   }
}

no errors appears in the log. In both cases all works fine.

Is there any errors in my dovecot's configuration?
