Cloudprint suddenly started crashing on startup

[Jeff K]

Cloudprint has been working reliably for more than a year on my Ubuntu 18.04 system.
Currently I have cloudprint-0.14-9 installed.
I am unaware of any recent changes to my system other than standard apt-get updates.

All of a sudden cloudprint stopped working... it stopped printing and https://www.google.com/cloudprint?authuser=1#printers showed my printers offline.

Whenever I try to restart, I get the following traceback error:

Traceback (most recent call last):
