Can't get it to run at non-default IP address

[etopian]

I tried changing the address

helixdns: -etcd-address="http://172.17.42.1:4001/"

helixdns -etcd-address="http://172.17.42.1:4001/" 2014/09/28 18:17:08 Starting server... 2014/09/28 18:17:08 Setting up watch to validate entries 2014/09/28 18:17:18 Panic in setting up watch on /helix. Is etcd running at http://172.17.42.1:4001/ ?

It works at the address, for instance I can get a key called mysql: etcdctl --peers 172.17.42.1:4001 get mysql 172.17.0.11

So there is a bug. I was using the latest stable etcd. etcd version 0.4.6
