Wield NullReferenceException when script access its own gameObject

Unity Engine
1

When we test our game on android phones, it sometimes throws NullReferenceException in this function, maybe once in ten times:

public void AddEventSwitchOwner(int slotID)
		{
			ViewEventSwitchOwner viewEvent = gameObject.AddComponent<ViewEventSwitchOwner>();
			viewEvent.Init(this, slotID);
			AddEvent (viewEvent);
		}

And the output log is:

Which I think is very wield, I mean, its accessing its own gameObject! how can it be null?

Is it possible when player left the scene, the gameobject is destroyed , but its component continue exist, so when he come back to the scene again, this script’s gameObject is null?

According to the docs

Actual object destruction is always delayed until after the current Update loop
