This was the idea behind adding the Finalize() call.  The errors that
you saw were due to the destruction of the containing window, whilst
the VTK components are reference counted and can't always be destroyed
at will.

When VTK 5 is released, all authors of widget set/VTK combinations
should adapt their code to take this into account.  Examples in VTK
will hopefully be updated as well.
