[vtkusers] Multiple vtkTkRenderWidget in python

[David Gobbi]

Hi Aude,

What version of VTK are you using?

Can you try loading the vtkTkRederWidget binary model before opening the
file dialog? For example, something like this:

    import Tkinter
    from vtk.tk.vtkLoadPythonTkWidgets import vtkLoadPythonTkWidgets
    vtkLoadPythonTkWidgets(Tkinter.Tk())
