[Paraview] GetSources() fails with Custom Filters

[Utkarsh Ayachit]

Matt,

I just tried the same with current git-master (should be same as 3.8
as far as python stuff is concerned). It seems to work just fine:

>>> from paraview.simple import *
paraview version 3.9.0, Date: 2010-05-21
>>> GetSources()
{('Sphere1', '105'): <paraview.servermanager.Sphere object at 0x4c3ffd0>,
 ('TwoShrinks1', '1111'): <paraview.servermanager.TwoShrinks object at
0x4c3fb10>}
>>>

Let me know if it doesn't work with  3.8 for you.
