[vtk-developers] vtkOpenGLTextActor/vtkTextActor exception error

[Allie Vacanti]

The only bit of extra setup that vtkTextActor requires is that the
vtkRenderingFreeType module needs to be linked, but it should print out
something like "Failed getting the TextRenderer instance!" if that's not
done, and vtkAlgorithm::SetInputDataInternal shouldn't be a part of the
stack.

What does the exception say? Can you provide a more detailed backtrace?
