[vtk-developers] Warnings with python 2.6, python guru wanted

[Francois Bertel]

Hi,

I already applied this patch on April 28, thanks for some internal
help at Kitware:
http://public.kitware.com/cgi-bin/viewcvs.cgi/Common/vtkPythonUtil.cxx?r1=1.90&r2=1.91

Good you answered anyway as it confirms the patch is correct.

Thanks!
