  Although without your kernel config and exact iptables ruleset I cannot
be sure, but I think you've found the same bug as Jonathan Cooper (and a
few others). See the thread about the problem on netfilter-devel:

http://lists.netfilter.org/pipermail/netfilter-devel/2004-March/014532.html

Basically, you should try two things:

- check if using CONFIG_IP_NF_NAT_LOCAL (NAT of local connections)
  solves the problem

- if i does, please try if Henrik's patch at 
http://lists.netfilter.org/pipermail/netfilter-devel/2004-March/014616.html
solves your problem

  To try the patch would be especially useful.
