Deleting set/SET rules by exact match fails

Deleting set/SET rules by exact match fails

[Born Without]

Hello list,

the problem I ran into is, that I'm unable to delete any iptables rule, 
which uses either the set match or the SET target, by the exact matching 
rule options. Deleting by rule number works though.
See below output.

System is Debian squeeze with debian kernel 2.6.32.
I downloaded the debian kernel source package.
Applied the netlink.patch and compiled/run it successfully.
Installed latest ipset successfully:

# ipset version
ipset v6.16.1, protocol version: 6

I tried to apt-src iptables and compile that, but made no difference.

# iptables -V
iptables v1.4.8

Any ideas on that?

Thank you very much!

It's an iptables issue - please upgrade/install newer iptables version.
