Internal error when changing scene

Hi there

I am getting this error after changing scene, it's all that it logged out to the console.

 ms_IDToPointer->find (obj->GetInstanceID ()) == ms_IDToPointer->end ()

I have a bootstrap scene that sets up a couple of things, like my game controller which is a singleton monobeahviour. When I load a level I check if this singleton exists and if not then I load the bootstrap scene, once the game controller has finished it's setup (in Start()) then I reload the original scene. I've not had any problem with this technique in the past. The issue seems to be when swapping back to the original scene. If i stop the loading of the bootstrap scene then the original scene loads fine. The same if i load into the bootstrap and then stop loading the original scene. And the same if i just load the bootstrap scene initially. The error only fires when swapping from the original scene to the bootstrap scene and then back again.

Level scene:

 void Start()
 {
     if (GameController.Instance == null)
     {
         Debug.Log("No GameController: Boostrapping from BattleController");
         Application.LoadLevel((int)SceneIds.Boostrap);
         return;
     }
 }

And my bootstrap game controller:

 void Start()
 {
     DontDestroyOnLoad(this);
             // do some other stuff
     Application.LoadLevel((int)SceneIds.GameBattle);
 }

Any ideas what could be causing this?

It doesnt seem to be causing any issues, it's just worrying that it's showing up in the error log and that I might be doing something bad.

Thanks
