I understand your point regarding Python versions but still I don't see any incompatible changes and commenting that line should not make differences.
I noticed something strange in logs that you shared to use. The memcache module used is coming from a package called "dogpile" /usr/lib/python3/dist-packages/dogpile where it should normally come from /usr/lib/python3/dist-packages/memcache.py
Can you try to log in a Python prompt, import "memcache" and then print the version and path?
My thinking is that there is a package conflict.
You should have something like:
(.py3) ubuntu@bug1812672:~$ python
Python 3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import memcache
>>> memcache.__version__
'1.57'
>>> memcache.__file__
'/usr/lib/python3/dist-packages/memcache.py'
(.py2) ubuntu@bug1812672:~$ python
Python 2.7.15rc1 (default, Nov 12 2018, 14:31:15)

>>> import memcache
>>> memcache.__version__
'1.57'
>>> memcache.__file__
'/usr/lib/python2.7/dist-packages/memcache.pyc'
