ClientResponseError after upgrading to latest version

[r0fls]

Long story short

After the release of the latest version of aiohttp our unit tests started failing here:
https://travis-ci.org/channelcat/sanic

Expected behaviour

The tests used to pass.

Actual behaviour

Some of our tests now fail with ClientResponseError("400, message='400, message='data received after completed connection: close message''",)

Steps to reproduce

This is only happening on travis.ci. I tried upgrading locally but the error doesn't occur there.

Your environment

Travis.ci with the latest version of aiohttp on python 3.5 and 3.6.

I'm just wondering if anyone has any hints that could help fix this, since I haven't had the time to dig into it very much.
