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

[Dr. Roman Grothausmann]

Dear mailing list members,


Attached is a very simple test.vtp (see *_01.png) which for some reason cannot 
be converted into a single vtkPolyLine with vtkStripper. Even if I use paraview 
with Clean+Triangulate+TriangleStrip the result still consists of two 
vtkPolyLine (see extracted cell 0 (thicker line) and green cell labels in 
*_03.png).
Why does vtkStripper not yield a single vtkPolyLine from this particular 
dataset? Is it the odd order of the points and lines?
Is this a bug?
If not, how can I achieve what I need, i.e. getting a single vtkPolyLine?

Any help or hints are very much appreciated
Roman
