IUIViewControllerTransitionCoordinator properties

The transition from portrait/landscape and landscape/portrait is not animated anymore.
This used to work on simulator and device but now only works on simulator.
I've set a breakpoint in the ViewWillTransitionToSize and on the IUIViewControllerTransitionCoordinator properties I get:
device: IsAnimated=false and TransitionDuration=0
simulator: IsAnimated=true ,TransitionDuration = 0.4/0.8
I could reproduce this with a blank UISplitViewController(overriden just to have acces to ViewWillTransitionToSize) that has set as ViewControllers 2 UINavigationController each having a UIViewController; 
in the FinishedLaunching I added the splitviewcontroller as Window.RootViewController;
in the splitviewcontrollers ViewWillTransitionToSize method I get iPadEmptyControlls.png.

Can you please provide the following information to help debugging the issue:

- A small sample that shows the issues.
- The complete information of you environment. You can find the information in the about dialog of visual studio. That way we will be able to pin point the exact version when this issue occurs.
