[Technology] One of the many reason why I dislike Python apps

AttributeError: 'CoreConfig' object has no attribute 'DATA_DIR'

So, on a clean install of GTG 0.2.9, which was released in February, it doesn't even start because an attribute gets referenced before it ever gets instantiated.  Yay.  This happens on almost every Python app I ever use at some point, and why I adore static type checking at compile time.
