more updates: NETFILTER_DEBUG catches the situation too - the problem
seems to be wrong reference counts on the skb. I've also added a few
printouts of ct fields:
NF_IP_ASSERT: include/linux/netfilter_ipv4/ip_conntrack.h:329(ip_conntrack_put)
NF_IP_ASSERT: net/ipv4/netfilter/ip_conntrack_core.c:346(destroy_conntrack)
NF_IP_ASSERT: net/ipv4/netfilter/ip_conntrack_core.c:346(destroy_conntrack)
BUG: NAT ct f0d6cf10 still hashed!
.. list empty ORIG: 0, REPLY: 0
.. expecting: 0
.. timeout pending: 1
.. ct_general: 0 [f0d6cf10]
.. nfct: f0d6cf10

i.e. we have ct->timeout still pending but the reference count is 0?
That cannot be right.
