My system is constantly being upgraded.  I am running the woody
(testing) distribution of Debian.  I have the same versions of XFree86
and tcl/tk as you but am using Python-2.1 (which I built from source).

The reason I never saw this problem earlier was that I never wrote
code that would do Tkinter.Tk() several times.  I was trying something
out when this happened and wrote a small test program that shows the
problem.

Unfortunately, there isnt any vtkTkRenderWidget or
vtkTkRenderWidget.so present in the VTK 4.0 tree.  Its all rolled into
libvtkRenderingPythonTkWidgets.so and linking to that seems no use.

Will try to take a closer look at the problem.
