[vtkusers] Core dump in Cube.cxx with vtk in RedHat7.0

[Tom G. Smith (B75826)]

In addition to tcl scripts failing, I get a similar core dump from
Cube.cxx, after installing vtk 3.1.2 on RedHat 7.0:

sh-2.04$ cp /opt/vtk/graphics/examplesCxx/Cube.cxx .
sh-2.04$ vud `which vtkbuildmake`
sh-2.04$ vtkbuildmake Cube
sh-2.04$ make -f Cube.make Cube
