RuntimeError: populate() isn't reentrant

I'm trying to make the Cointrol work on a Raspberry PI 2. I'm following the instructions from the README until cointrol/manage.py syncdb --noinput, which gives me an error: https://gist.github.com/Lunatic666/093f09a614ad8bbd16d6

I'm executing everything as non-root user on a Python 3.4.3 environment

AttributeError: module 'html.parser' has no attribute 'HTMLParseError'

I'm following the install instructions and I'm stuck in this error:

Needs some updating

To run this on windows, I've had to update npm packages
"brunch": "2.10.16",
"handlebars-brunch": "2.10.0",

and python packages
hiredis==0.2.0

And also your readme is lacking
python setup.py develop to run the app in development mode.

And I haven't been able to solve the SSL error I'm getting upon authentication with python 3.4:

File "**\cointrol\env\lib\site-packages\tornado\iostream.py", line 1310, in _do_ssl_handshake self.socket.do_handshake() File "C:\Python34\Lib\ssl.py", line 767, in do_handshake self._sslobj.do_handshake() ssl.SSLEOFError: EOF occurred in violation of protocol (_ssl.c:598)

Does it work nowadays?

Just an open question!
