NullReferenceException error in iTween.cs

[GoogleCodeExporter]

This error happens when I import iTween.cs into any project:

NullReferenceException: Object reference not set to an instance of an object
iTween.LateUpdate()(at Assets/iTween/iTween.cs:6583)

The program still runs but this error stays in the console. 

Unity 3.4.2f2
Win7 64 bit

I ran into this as well, and have a fix I think does the trick.

Inside LateUpdate(), switch the order of the checks so it looks like this:
if(isRunning && tweenArguments.Contains("look target"))
Also, set isRunning=false before every call to Destroy(this); (especially in 
Dispose())

Actually, I think if you save any code file, even if you only removed some 
whitespace, while Unity is running it seems to trigger this, but not otherwise. 
 However, it seems to not only affect iTween; other objects of mine get 
destroyed as well.

This post suggests making data serializable can help avoid this problem, so 
maybe that's something iTween can do?

For now, restart your game after making any code file changes.
