Issue with scripts/0.5.1

[gitbase1]

Running commands with "piston" is working fine, but utilizing a script after steem 18 and 0.5.1 is broke.

import os
import json
import threading
import random
import time
import datetime

from steem import Steem
from time import localtime
from steem.post import Post
from random import randint

then getting this when streaming

for c in steem.stream_comments():

error happened <class 'AssertionError'> ()

Thanks
