[Paraview] Issue with ParaView and python

[Michael Reuter]

Hi,

     I'm trying to use the ParaView (latest git version) python API from 
within pure python and I'm running into an issue. The script I'm testing 
runs the sphere animation example from the PV wiki, and while the 
animation shows fine, the script crashes at completion on both Ubuntu 
12.04 and OSX 10.8.4, with slightly different error reporting. 
Everything works fine if I use pvpython (both with and without wrapper 
script), but I don't see why pure python should be a problem. I've 
attached the wrapper script I use to setup the environment (taken from 
suggestions on PV wiki) and the script I'm testing. Below, I've shown 
the errors seen. Has anyone seen this before? Is there some extra setup 
bit that pvpython is doing that isn't being taken care of by the wrapper 
script?

Thanks,
M

     On Ubuntu, I usually see the following error:

*** glibc detected *** python: corrupted double-linked list: 
0x0000000003064250 ***
Occasionally, I'll get:
*** glibc detected *** python: double free or corruption (!prev): 
0x0000000003cd12a0 ***
and a long error report.

     On OSX, I see:
