[vtkusers] Writing a file

[Bill Lorensen]

In VTK6, SetInput is gone! You did the right thing by changing it to
SetInputConnection. (BTW, SetInputConnection works in VTK5 also).

Try removing your VTK build tree and rebuilding vtk. Something strange
is going on, perhaps elsewhere in your code. I assume that the input
file is a vtk polydata file?
