Thanks for your comments Prabhu. My problem is solved:

It's necessary to call vtkDataArray.SetNumberOfComponents() and
vtkDataArray.SetNumberOfTuples() **after** vtkDataArray.SetVoidArray()

I think this is a highly non-obvious gottcha (with nothing indicated in
the docs that the ordering is important), so I'm CC-ing this to the
user-list in case anyone else gets stuck no this problems...

Cheers,
Bryan
