[python-win32] 'No such interface supported' error after makepy

[Jens B. Jorgensen]

It's probably something to do with the office automation components 
rather than Python I'm guessing. The error really seems to indicate that 
the object that is instantiated is saying that it doesn't support the 
IDispatch interface. This is weird but I have seen weirder things happen 
for no reason (i.e. COM registry entries getting mangled with bizarre 
entries for no reason causing strange errors to occur).
