PyArg_ParseTuple and dict

[sjh at gmail.com]

I'm trying to write an extension for python 2.4, and I can't seem to
get PyArg_ParseTuple to work with a dict.  I've tried all sorts of
things, but the most simple thing that fails is:

[...]
  if (!PyArg_ParseTuple(args, "O",  &file)) {
        return NULL;
  }
[...]


If I call the function from python with an int, or a string, etc it
works fine.  If I pass in a dict I get:

SystemError: new style getargs format but argument is not a tuple


even though a call to:
PyObject_TypeCheck(args,  &PyTuple_Type)

tells me that args is a tuple.  PyObject_Print(args, stdout, NULL) even
produces:

({'foo': 1},)

Can anyone give me a minimal example of a C function that takes a dict
and parses it out with PyArg_ParseTuple?
