iptables error using limit module

["Marc Franquesa" <marc.franquesa@gmail.com>]

I'm reconfiguring the netfilter firewall after reinstalling my SGI O2.

I'm using the ruleset saved from another computer
(iptables-save/iptables-restore) and I got the error:

ip_tables: limit match: invalid size 40 != 32

Then I tried to build the ruleset by hand entering the comands one by
one using iptables.

I found that the errors appears only when I'm trying to use the 'limit' module:

idoru:~# iptables -I INETIN -p icmp --icmp-type 8 -m limit --limit
1/sec --limit-burst 5 -j ACCEPT
iptables: Invalid argument

And in the kernel messages (dmesg) appears this:

ip_tables: limit match: invalid size 40 != 32

I don't know if this is the correct list to post this topic, but I
have an other Debian etch on another computer and works perfectly, and
fails on mips with this message.

I haven't found anything on google.

¿Any suggestions?
