TypeError: __call__() takes 3 positional arguments but 4 were given

I use Qt 5.5.1/ PySide2 and dev version of ghost.py.
When I'm trying to use example like
`from ghost import Ghost
ghost = Ghost()

with ghost.start() as session:
page, extra_resources = session.open("http://jeanphix.me")
assert page.http_status == 200 and 'jeanphix' in page.content`
I'm getting this traceback.

But just now I tested it in console and all works perfect :/

And I use Python 3.5.
It looks like some basic bug, but its strange. Looks only I got it...

i got some exception too with session.open('http://opu.ua'), but it works, for example, with session.open('http://ac.opu.ua')

I get the same error, but not every time. Sometimes it works to fetch data.
Python 3.6.3
PySide2
Qt5.9

@jeanphix care to chime in? I'm getting the same bug using the official docker image. Here's the code and traceback:

from ghost import Ghost
