QTILE - File paths in widgets break qtile

Hello.

I'm trying to make use of Qtile's BatteryIcon widget.

Part of the doc states that I can pass a 'theme_path' arg in the widget function. Whenever I specify a path and restart qtile, qtile will only render the current screen and a cursor. Keys and Bar disappear until I remove the path from config.py and restart the qtile session.

Troubleshooting:

• I know my syntax is correct, because I can execute 'python3 config.py' without any errors
• qtile.log does not produce any relevant information either
