"Failed to load dataset" + "Camera authorization"

On iOS8 (maybe that happens on lower OS too), when you try to access the camera on an app the first time, the OS prompt a popup "Do you authorize the application XYZ to access your camera?".

If you launch the Vuforia view on an app where you've not yet authorized the camera, the lacunh failed with the following error "Failed to load dataset". I tested on SDK v3 and SDK v2 of Vuforia.
