Subject: NULL pointer deref using bridge and bridge-nf-call-iptables = 1

Hi,

i'm getting "BUG: unable to handle kernel NULL pointer dereference at 0000000000000134" when 
using bridge with bridge-nf-call-iptables = 1. When i set bridge-nf-call-iptables = 0 problem goes away.
I'm using 2.6.38-gentoo-r1, but the same problem was in 2.6.37. 2.6.35 hasn't this bug. I can't reproduce 
this problem, because it happens random, sometimes after a day and sometimes after few minutes. 
So i hope that trace will help. Iptables haven't any rules and br0 hasn't any ip address.
 If you need more info just say what do you need.
