[pygtk] Codegen/argtypes: "No ArgType for GValue*" on Linux & Windows

[David ROY]

Hi Dieter,

I installed the built binaries you provide for windows:
20101102/pygoocanvas-0.14.2.win32-py2.6.msi

But no one of the libgoocanvas-3.dll I tried seems to fit with the
goocanvas.pyd, I always end up with:

>>> import goocanvas
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: DLL load failed: The specified procedure could not be found.

I got the goocanvas dlls from
http://ftp.gnome.org/pub/GNOME/binaries/win32/goocanvas/
These dlls were working with the goocanvas.pyd I had compiled by myself.

Am I missing something?
I think I'll go and see your changes in pygobject and pygtk, I'm very
curious to understand :-)

Thanks
-David
