There are 2 reasons this is happening.  If the IDL correctly
said "IDictionary" instead of IDispatch, _or_ the IDictionary
implementation of IDispatch supports type info, then makepy would know
exactly what the object is.

However, as neither of these are true, Python knows nothing more than
it is an IDispatch.

This is win32com mis-leading you.  It tries to use the "name" of the
object, and without any type information or other hints, it uses the
name of the method or property.  This often works quite well - eg, if
instead of a method called "getDictionary" it was simply a property
named "dictionary" it would make much more sense.

I have no idea why this is failing.
