Unfortunately the "original" bug is hidden.

This bug is triggered, because the global property "prop.user_dir" is set to None in
file "/usr/share/hplip/base/g.py" line 165 ff:

  else:
            # If running as root, conf file is None
            prop.user_dir = None
            prop.user_config_file = None
            ConfigBase.__init__(self, None)
