 I've seen this on a newly installed sarge with a slight difference: the
 IPv6 packets would not leave the box, but the IPv6 would try to
 autoconfigure itself and send packets on its subnets.

 I think (at least in my case) deactivating autoconfiguration when none
 is possible is enough, and this is probably possible via
 /etc/sysctl.conf.
