[Paraview] Core dump from pvbatch

[Iain Bethune]

When I run a python script that renders images in a loop and writes them out
as PNGs I always get a core dump on the second time around the loop:

Starting iteration 0

done

If I remove the step to save the file, it runs fine, and outputs all the
iterations in an X Window as expected.

The script is attached. I'm using PV 3.2.1 on AIX 5.3 - the X server is
cygwin forwarded over PuTTY SSH.  Any ideas what might be wrong?

Cheers
