# chkconfig ip6tables off
will probably stop this from occurring. looks like
/etc/init.d/ip6tables invokes /etc/sysconfig/ip6tables-config then if it
finds them, /etc/sysconfig/ip6tables .. the -config file just sets some
environment variables, so probably doesn't take more than a blink, while
/etc/sysconfig/ip6tables is going to attempt to set whatever firewall
rules are in there.
