The code in "cDocumentTemplate.c:MM_cget" checks whether
the object is a "dict" and in this case calls
"PyDict_GetItem". This function ignores your "__getitem__" customization
(and directy uses the dict's "__getitem__").

You can replace "dict" above by
"UserDict" (from module "UserDict") and the problem disappears
(as then the "PyDict_Check" will return "false").
