rotated / animated the default cube to get some motion
rendered frame 3
Now it took some time to render, but the result was not visible.
There was a image created called "__motion_blur_temp" (which i can see if a switch an image/render view to that image) but that was not connected anywhere in the compositor (as opposed to what it sounds in the documentation).
The rendered image "__motion_blur_temp" looked ok btw.
Just tried your addon like this:
