Order of imports and method calls alters API

[Christopher Lee]

Using the python gi.repository (gir1.2-gtk-3.0) if I import Gdk make a specific method call and then import GdkX11 the API for GdkX11 is different than if I had imported both before the method call.

To reproduce:
Run the script found here (details in comments): http://pastebin.ubuntu.com/7801425/

 - Running the script without any arguments passed (i.e. the API is as expected)

 - Running it with any arguments will make the script call 'Gdk.get_default_root_window()' before the import of GdkX11 meaning the call of 'GdkX11.X11Window.foreign_new_for_display(...)' will fail with the message:
  AttributeError: type object 'gtk.gdk.X11Window' has no attribute 'foreign_new_for_display'
