IPSET iptree problem

["Łukasz Nierychło" <nofast@welnowiec.net>]

Hello everyone,
I would like to ask you to help me with ipset tool
because it works other way I expect when I use "timeout"
parameter.

look:  (this is OK without "--timeout")
[root@rt ~]# ipset -N ts1 iptree
[root@rt ~]# ipset -A ts1 10.10.10.10
[root@rt ~]# ipset -T ts1 10.10.10.10
10.10.10.10 is in set ts1.
[root@rt ~]# ipset -T ts1 10.10.10.1
10.10.10.1 is NOT in set ts1.
[root@rt ~]# ipset -T ts1 10.10.10.255
10.10.10.255 is NOT in set ts1.

My question is what I did wrong here:
"--timeout" is used:

[root@rt ~]# ipset -N ts2 iptree --timeout 100
[root@rt ~]# ipset -A ts2 20.20.20.20
[root@rt ~]# ipset -T ts2 20.20.20.20
20.20.20.20 is in set ts2.
[root@rt ~]# ipset -T ts2 20.20.20.1
20.20.20.1 is in set ts2.
[root@rt ~]# ipset -T ts2 20.20.20.254
20.20.20.254 is in set ts2.
[root@rt ~]# ipset -T ts2 20.20.1.1
20.20.1.1 is NOT in set ts2.

If I use "timeout" then ipset test returns true
to all IPs on subnet 20.20.20.0/24.

Shouldn't this work the same way ( as without "timeout" )?
Is this ok  ?

my linux = kernel-2.6.21.1
+ set patch (pom-ng-20070513)
+ ipset-20070514

Help me please
