But no matter what I do I always get this error :

$ nitpick.py
/home/px/scripts/nitpick.py:157: GtkWarning: Attempting to add a widget with type GtkVBox to a GtkWindow, but as a GtkBin subclass a GtkWindow can only contain one widget at a time; it already contains a widget of type GtkScrolledWindow self.window.add(vbox)
