Docker doesn't start any single image... iptables error - bug?

No matter what kind of image I load, I always get an error like this:

Fehler: {"message":"driver failed programming external connectivity on endpoint memcached (2897024ee33b748d9ce66273e81b5a0af0ba9aa08f286922a19363e4071095c8): (iptables failed: iptables --wait -t filter -A DOCKER ! -i docker0 -o docker0 -p tcp -d 172.17.0.2 --dport 11211 -j ACCEPT: iptables: No chain/target/match by that name.\n (exit status 1))"}

What am I supposed to do to resolve this?

Thanks.
