In my experience, getItem will return None if *anything* goes wrong
with data retieval or object creation.  Sometimes you get a traceback in
the STUPID_LOG, and sometimes you don't (and I haven't figured out the
pattern yet).  Test everything you can independently, and simplify
everything to the bare minimum until you get it to work, and then
add back the other variables, etc.
