Answer 1

Problem

When you call new GUITexture() Unity will just make your temp object null. Then when you try to use it you get a NullReference Exception. Why? Because GUITexture inherits from Behaviour, it is just the way Unity is built.

Solution

You are already dragging your reference to the GUItexture via the editor, so all you need is to remove this line.

// Remove this line
temp = new GUITexture ();
