You're right that there's a bug in the 0.91 code, however, the real 
issue is in
the cluster.get_cluster code. This code was attempting to fetch the
key_location from the config and I was not handling the case that the keypair
might not be defined in the config. Marc Resnick and I discovered this bug a
couple weeks ago when we attempted to use different keypairs to launch our own
clusters on the same account and neither of us had each other's keypairs
defined in the config. The code in github fixes this issue and should be
released soon.

Thanks for reporting,
