[Paraview] camera commands hang in python script

[Iain Bethune]

Interestingly, I tried today executing the same script using pvbatch and it
works fine, it just seems to hang when using the python shell in the GUI.

I'm experiencing the same problem, both on Windows and Linux. Has anyone
been able to use python scripting to manipulate the camera?

Thanks!
