does not work with dockerrun 0.1.2 and docker 1.12

[chanezon]

When I click vote for cats, or dogs, I get a 500 error, and this in the logs.
This was built with the latest dockerrun https://github.com/bfirsh/dockerrun/blob/master/dockerrun/client.py with the fix for 1.12. It seems the 1.12 fix introduces a new error.
