RequireComponent not working!

I have a script that requires a Camera. It loads itself when calling one of its static methods:

 [RequireComponent(typeof(Camera), typeof(GUILayer))]
 public sealed class SomeManager : MonoBehaviour
 {
     static SomeManager()
     {
         new GameObject("SomeManager", typeof(SomeManager));
     }

It works very well when I'm on editor, but when I compile to Windows Store Apps, I get a null reference exception on Awake:

 private void Awake()
 {
     camera.cullingMask = 1 << LayerMask.NameToLayer("Background");

Because camera is null! This is a bug, right?
