[vtk-developers] vtkExecutive::GetInputData: error message necessary?

I just noticed that doing something like this:
>>> import vtk
>>> w = vtk.vtkWarpScalar()
ERROR: In /skratch/prabhu/vtk/cvs/VTK/Filtering/vtkExecutive.cxx, line 478
vtkStreamingDemandDrivenPipeline (0x824b198): Attempt to get input data for connection index 0 on input port 0 of algorithm vtkWarpScalar(0x824b248), which has 0 connections.
The method returns None as before (VTK-4.4). The warning seems
unnecessary to me. There are a bunch of other methods which do not
produce such a message and therefore the message is also inconsistent
with what other methods do. For example:
which all do not produce any error messages. I would therefore think
that the error message is unnecessary and just an irritant. Can this
error message be removed?
