Some netfilter log messages are missing a log prefix

Hi list,

I added logging rules to all of netfilter's built-in chains using the following script:

https://gist.github.com/anonymous/5330491

All logging rules get the correct --log-prefix argument (verified by using "iptables -t table -L -n -v" commands; also verified that there are no other logging rules present).

Why do I still get some log messages in syslog that don't have a log prefix at all?

Additional info:

# iptables --version
iptables v1.4.14
# uname -a
Linux debian 3.2.0-4-amd64 #1 SMP Debian 3.2.41-2 x86_64 GNU/Linux

Thanks.
