TypeError: unsupported operand type(s) for +: 'int' and 'str'

I solved by doing the following:

Line 475 replace:

try:
  bytes = http_response.read(content_length)
except:
  bytes = http_response.read()

If an empty Content-Length header is received then the whole body will be read, if a non integer is read then a ValueError is raised

Looks good to me, please merge.
