Hi!

Is here any expert who knows how to use vtk from python?  I'm writing a unit
test for out vtkwriter, and I would like to check the produced vtk files by
loading them into vtk.  I currently have the following python script:
======================================================================
#!/usr/bin/python

from vtk import *

reader = vtkXMLUnstructuredGridReader()
reader.SetFileName("fs1539test.vtu")
reader.Update()
======================================================================

There is a broken vtk file attached.  When I try to load that file from this
vtk skript I get an error message on stderr.  But I cannot get python to tell
me that loading failed.  Ideally I'd like to "exit(1)" if loading has failed.

Anyone has hints?

Regards,
Jö.
