[vtkusers] Crash with subsequent creation of vtkRenderWindow in Python

[Pearu Peterson]

Hi,

The following Pyhton code

"""
from vtk import vtkRenderWindow
win = vtkRenderWindow()
win.SetSize((400,400))
win.Render()
raw_input('Press any key to close window: ')
del win
raw_input('Press any key to create a new window: ')
win = vtkRenderWindow()
win.DebugOn()
win.SetSize((400,400))
win.Render()
raw_input('Press any key to exit: ')
"""

crashes with the following output:

"""

I am using VTK from its CVS and Mesa 5.0.1, both built
with gcc-2.95.4 on Debian woody.

Is the above Python code buggy or is it VTK or Mesa bug?
What is the correct way to close a RenderWindow and open another one?

I have noticed that there is no problem if to create several
subsequent RenderWindows but whenever one is closed before opening
another RenderWindow, this crash occures. Any ideas?

Thanks,
