The following crashes on a host with no IPv6 connectivity:

Python 3.8.2 (default, Mar 13 2020, 10:14:16)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import httplib2
>>> httplib2.debuglevel = 1
>>> h = httplib2.Http()
>>> h.request("")
Traceback (most recent call last):
  File "/home/cjwatson/src/python/httplib2/python3/httplib2/", line 1324, in connect
    sock.connect((, self.port))
OSError: [Errno 101] Network is unreachable

During handling of the above exception, another exception occurred:

    print("connect fail: ({0}, {1})".format((, self.port)))
IndexError: Replacement index 1 out of range for positional args tuple

This is because there's one more layer of parentheses in that str.format call than there should be. The Python 2 version doesn't have the same bug.
