Problems with SID, postfix 2.1.1, amavis after update

[Jochen Kaechelin <debianfreak@freenet.de>]

I use these debs:

	postfix 2.1.1-3
	amavisd-new 20030616p7-3

--------------------------------
main.cf 

	content_filter                 = smtp-amavis:[127.0.0.1]:10024
--------------------------------
master.cf 

smtp-amavis unix -      -       n     -       2         smtp
    -o smtp_data_done_timeout=1200
    -o disable_dns_lookups=yes


127.0.0.1:10025 inet n  -       n     -       -         smtpd
 -o content_filter=
 -o local_recipient_maps=
 -o relay_recipient_maps=
 -o smtpd_restriction_classes=
 -o smtpd_client_restrictions=
 -o smtpd_helo_restrictions=
 -o smtpd_sender_restrictions=
 -o smtpd_recipient_restrictions=permit_mynetworks,reject
 -o mynetworks=127.0.0.0/8
 -o strict_rfc821_envelopes=yes
--------------------------------

everything works great using postfix 2.0.19 (the last deb in 
unstable after the release of 2.1.1) and after the update
i get the following errors:


warning: /usr/lib/postfix/smtp: bad command startup -- throttling

when I remove the this line

	content_filter                 = smtp-amavis:[127.0.0.1]:10024

everything works fine again!

any suggestions?
