[vtkusers] vtkTkRenderWidget alloc invalid block

[Angelo Tardugno]

Hi everybody,

I'm experiencing a problem with vtkTkRenderWidget I just run this command in
the python interactive mode (to see if it works)

>>> from vtk import *
>>> from Tkinter import *
>>> from vtk.tk.vtkTkRenderWidget import *
>>> root = Tk()
>>> pane = vtkTkRenderWidget(root,width=600,height=480)

at this point I've got an error saying

alloc: invalid block: 033C9F90: 1 0

and a runtime error causes python to exit...

Any idea why this is happening?

Thanks

Angelo Tardugno
