I'm not immediately sure whether the real problem is the TypeError in parse_bool or the AttributeError in is_url. The error in is_url seems strange, because it reports that module 'urllib' has no attribute 'parse' despite that module having been imported in the same file.

taucmdr/packages/taucmdr/util.py

Line 46 in 28a994d

import urllib.parse

It looks to me like the urllib error in is_url is the real issue. The TypeError exception in parse_bool is being caught and that is why is_url is called. Is this reproducible? I haven't been able to reproduce this issue yet.
