[StarCluster] ERROR - "Incorrect padding" in listclusters command (github version)

[Kyeong Soo (Joseph) Kim]

Justin,

Today I tested this with the newest version from github and
encountered exactly the same error (i.e., incorrect padding) as
before.
To make sure, I started from scratch (including new configure file
from the new version of starcluster), but the result was the same.

By the way, it doesn't matter whether there is any running cluster or not.

Regards,
Joseph
