Crash related to coroutines

[jamiestepanian]

I'm getting the following crash after the json printout (-j flag):

/home/vec/pyfido/pyfido/client.py:317: RuntimeWarning: coroutine 'ClientSession.close' was neve
  self._session.close()
Unclosed client session
client_session: <aiohttp.client.ClientSession object at 0x7efcadfcf7b8>

connector: <aiohttp.connector.TCPConnector object at 0x7efcadfcf7f0>

with no json flag, I get this:

I tried debugging it, but my knowledge of python coroutines is lacking.
I'm using a python 3.5 virtualenv (as instructed). Running from Linux.
