New Behavior: starcluster addnode error from StarCluster-created master instance

Hi Starcluster Friends!

Just today I heard from a user that he was having trouble adding nodes from the master of a StarCluster created cluster. The AMI is StarCluster public 64-bit Ubuntu EBS non-HVM (ami-765b3e1f in us-east-1). These instances have been working reliably this way for many months, so it seems like something has changed at AWS? Anyone know of anything?

Running default StarCluster 0.95.5
The behavior: locally (not from in EC2) I can add nodes just like normal. From the master, I get this:

$ starcluster an mycluster -a node001
StarCluster - ( (v. 0.95.5)

Any thoughts? Anyone else seeing this?
