Yup. I do. The versions of ParaView and VTK you are using do
not match. For now, replace whatever streamline filter is in
the script with either vtkPStreamTracer or vtkDistributedStreamTracer
(depending on the version of VTK you are using, try both)
and the problem should go away. You can use the same in Java
(as long as you enable the parallel option, that is)

In the next release, ParaView will not write VTK
scripts but Tcl scripts to be executed by ParaView (not VTK) to avoid
such problems.
