I'm not sure whether this is the recommended solution, but the following
works: 

from gi.repository import GObject, Clutter
class Editor(Clutter.Box):
    def __init__(self):
        super(Editor, self).__init__(layout_manager=Clutter.BinLayout.new(4,4))

The __init__function of GObject (which is GObject.Object in python, not
as you wrote in your "also does not work" example) is more or less the
same as g_object_new in C, and the new functions are just for
convenience. This is not very pythonic, but this is how GObject works.

HTH,
