yes but it doesn't do what you think: it rebinds the name `self` to the
builder object but the other references point to the `ActionsMenu`.

what you can do is something like the following:

	class BaseWindow(object):

		def __init__(self, builder, auto_connect=True):
			self.__builder = builder
			if auto_connect:
				builder.connect_signals(self)

		def __getattr__(self, n):
			w = self.__builder.get_object(n)
			if w is not None:
				return w
			raise AttributeError, n

or even, but not tested:

		...
		def __getattr__(self, n):
			w = self.__builder.get_object(n)
			if w is not None:
				setattr(self, n, w) # here the point
				return w
			raise AttributeError, n

m.
