[Paraview] vtkClipDataSet in a programmable filter

[Cory Quammen]

Xavier,

The runtime error is troubling. I suspect there may be a problem or
incompatibility with a shared library on your system.

If you wanted to debug further, you could try downloading Dependency Walker
[1] and load paraview.exe with it. It should show you the DLLs ParaView is
trying to load. I wonder if ParaView is trying to load a Python other than
the one it ships with?

HTH,
Cory
