python3 venv - Exception: expecting STREAM_START in streamStart, instead got token: failure

[peletiah]

yowsup2 does not appear to work under python3 at the moment:

I've created a fresh virtualenv:

python3 -m venv env_python3
cd env_python3
bin/pip install yowsup2
bin/yowsup-cli demos -d --login 4915XXXXXXXX:LvdlXXXXXXX+XXXXXX649a4= -s 43680XXXXXXX6 'Testasdfsdaf'
[..]
Exception: expecting STREAM_START in streamStart, instead got token: failure

Here's the full debug output:

yowsup-cli  v2.0.15
yowsup      v2.5.0
