Charl,

I only didn't add the renderer because I was trying to get the minimal
script that would crash. Running wxVTKRenderWindowInteractor directly also
crashes:

[doriad at davedesktop wx]$ pwd
/home/doriad/src/VTK/Wrapping/Python/vtk/wx
[doriad at davedesktop wx]$ python wxVTKRenderWindowInteractor.py
Segmentation fault

Any thoughts on what to try next?

Thanks,

David
