Error Message "nfnl_talk: sendmsg(netlink) Message too long" by test.c

Problem: Error Message "nfnl_talk: sendmsg(netlink) Message too long" when running test.c programm.

My System is 2.6.18-5-ixp4xx on a NSLU2 ARM CPU.
I installed libnetfilter_queue and libnfnetlink from debian rep. by tipping apt_get install libnetfilter_queue1.

I also installed it manually with apt-get. But i still got the same Problem.
On other Hand i installed it on my desktop and it worked great.

I have not found same error msg on the net.

Test Env.

LKG995999:~# modprobe ip_tables
LKG995999:~# modprobe iptable_filter
LKG995999:~# iptables -A INPUT -s 192.168.2.1 -p TCP -j QUEUE
LKG995999:~# gcc route.c -o test_nfq -lnetfilter_queue
