Oh, hmm, this is because we don't automatically open connections to brokers as returned from the new Brokers() method (#813). If they haven't already been talked to for some other reason you'll get this error. @hollow I'm kind of surprised you haven't run into this.

As a short-term workaround, just call Open() on each broker before calling ListGroups (and ignore any ErrAlreadyConnected). In the longer term we should probably either open all the brokers before we return them or at least document this behaviour.

Thanks,call Open() before other operations are ok!
