Libcloud ECS access - driver

Question

trying to test out the ECS driver of libcloud for a project.
i wrote a simple test:
with open("conf.json") as f:
data = json.loads(f.read())
driver = get_driver(getattr(Provider,'ECS'))
with open('.cloud_credentials/'+data['provider']+'/access_id', 'r') as myfile:
ACCESS_KEY_ID = myfile.read().replace('\n', '')
print ACCESS_KEY_ID
with open('.cloud_credentials/'+data['provider']+'/secret_key', 'r') as myfile:
SECRET_KEY = myfile.read().replace('\n', '')
print SECRET_KEY
timer.start()
conn = driver(access_id = ACCESS_KEY_ID,
secret = SECRET_KEY,
region = 'us-east-1')
timer.stop()
cluster = conn.create_cluster('pippo','us-east-1')
However running it produce this error:
Traceback (most recent call last):
File "launch.py", line 32, in <module>
cluster = conn.create_cluster('pippo',data['region'])
File "/home/sergio/anaconda2/lib/python2.7/site-packages/libcloud/container/drivers/ecs.py", line 151, in create_cluster

I Think that the problem lies with the host string, containing that %s. Digging in the library looks like that string is a dummy one initialized in the file:
/libcloud/container/drivers/ecs.py
I suppose that there should be somewhere in those files a function supposed to overwrite the base-string, that probably doesn't get called for some reasons but, being a novice with the libcloud library, makes it kind of difficult to find the culprit.
Curiously, inspecting the headers that are being sent, looks like they contain the correct(?) address there:
headers: {'Host': u'ecs.us-east-1.amazonaws.com', 'User-Agent': 'libcloud/2.2.1 (Amazon Elastic Container Service) ', 'Content-Type': 'application/x-amz-json-1.1', 'Accept-Encoding': 'gzip,deflate', 'x-amz-target': 'AmazonEC2ContainerServiceV20141113.CreateCluster'}
Anyone with more experience could point me in the right direction? It would be much appreciated.

This looks like a bug, it's not something you've done.
