So then how do you know isinstance is evaluating to False?  And why do
you return None if it evals to True?  Can you drop a print command
inside the if block just before returning None, and another print just
before returning the default default?

I also would recommend using a debugger like winpdb when in a spot
like this - despite the name, it is not Windows-only, and you can step
through this code and evaluate variables and expressions inline.
