[Paraview] Unable to generate animations with pvbatch

[Kent Eschenberg]

Utkarsh,

As per your suggestion (at the bottom of this message) I added this call to the pvb file created by paraview 2.4.4 (running on Redhat Linux Fedora Core 5 and a Pentium 4):

   $pvTemp115 SaveImages test jpg 1920 1080 5 90

For testing, I ran pvbatch directly, on my workstation. The script creates a sphere; cuts it; and then animations the offset for the cut. Here's the output:

======
$ pvbatch anim.pvb
Process SphereSource [...........]
Process PVClipDataSet [...........]
Process DataSetSurfaceFilter [...........]
Segmentation fault (core dumped)
======

Here is some information from gdb, edited a little for readability. Note that the value of "this" at level #0 is null!

Are there commands I can add to the pvb file to update something or otherwise avoid this problem? Thanks in advance for your help!
