Blender Version

When playing the animation in the file for some invocations of the pre frame change handler,
the custom property 'CustomProperty' of object 'Cube' does not seem to exist .

Exact steps for others to reproduce the error
Open attached file:

RenderNotAnimatedBug.blend573 KBDownload

Make sure the script Handler.py is executed at least once
open the system console
play animation to make sure the custom property of Cube is updated (Cube also changes color according to property).
Note the error messages that on some invocations the custom property does not exist:

File "C:\...\RenderNotAnimatedBug.blend\Handler.py", line 7, in animate_cube
KeyError: 'bpy_struct[key]: key "CustomProperty" not found'

I think that the root cause might be the same as in your other report to let's merge them for now.
