[Paraview] VRML import failing

[Scott Vorthmann (personal)]

(Sorry if this is a duplicate... I think the last one might have  
failed.)

I'm trying to import a VRML file, but it appears that there's  
something amiss with the importer itself.  This is from the Error Log:

vtkCompositeDataPipeline (074FF490): Input port 0 of algorithm  
vtkVRMLSource(074FBA50) has 0 connections but is not optional.

Any suggestions on how (or if) I can remedy this problem?

Thank you,

Scott Vorthmann
