iOS 7, UICameraPickerController, crashing when device is laying horisontal (on the desk)

When i make this:

UIImagePickerController picker = new UIImagePickerController (); picker.SourceType = UIImagePickerControllerSourceType.Camera; PresentViewController (picker, true, null);

I get application output: Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.

Camera picking View actually appears, but when i press on Capture button, app crashes and i get application output as I mentioned above. On iOS 6 it works perfectly without any warnings or crashes.
