[vtkusers] vtkStripper/TriangleStrips not working on this particular data, why?

[Goodwin Lawlor]

Hi Roman,

Your question crops up on the list every so often. vtkStripper doesn't
guarantee the minimal number of polylines from a dataset...

See this 2002 post, that contains a patch which may help:
http://vtk.org/pipermail/vtkusers/2002-January/009372.html

There was a bug report too:
