Script with StopByName generates EXC_BAD_ACCESS when using across several scenes

What steps will reproduce the problem?
1. create 2 scenes each with a gameobject executing code example below
2. starting first scene makes everything work as expected (doesn 't matter 
which scene you start first)
3. Application.LoadLevel (second scene) and run second scene. Call 
SetInitParams(). This will throw error (see below)
4. Build with script call optimisations  "fast but no exceptions"

What is the expected output? What do you see instead?
expected: Stopped iTween with name "rotatebyXYZ". Starting DelayedTween().
instead: something goes wrong with tween destruction.

What version of the product are you using? On what operating system?
2.0.44 with Unity 3.4b4, OSX 10.6.7

Please provide any additional information below.
