Message 99522 - Python tracker

I'm trying to figure out the attached script.  If I run Python 3.0, the script doesn't run because of the undefined gc.DEBUG_OBJECTS.  If I just remove that, the script runs without error.  Does that mean the problem is fixed?  Or is running without an error an example of the problem?

If I add gc.DEBUG_SAVEALL, it fails--but that seems obvious because DEBUG_SAVEALL adds all objects with finalizers to gc.garbage.
