"/usr/lib/python3.6/configparser.py", line 989 looks like:

    def __iter__(self):
        # XXX does it break when underlying container state changed?
        return itertools.chain((self.default_section,), self._sections.keys())

Does python not have the equivalent of package-lock.json used npm for JS which avoids having incorrect versions of dependencies break builds?

Btw, according to configparser documentation, the default value of default_section should be 'DEFAULT'.

default_section, default value: configparser.DEFAULTSECT (that is: "DEFAULT")

It seems for whatever reason this default value is not being set. Adding it to line 29 (top of class KazamConfig definition) in /usr/lib/python3/dist-packages/kazam/backend/config.py fixes the issue.

default_section = "DEFAULT"

I don't really know python, so there may be reasons why this shouldn't be done? or there may be a better solution?
