[vtkusers] wxVTKRenderWindowInteractor segfaults

[Dominik Szczerba]

More debugging:

using wxVTKRenderWindow instead of wxVTKRenderWindowInteractor seems
to work correctly, but does not allow, e.g., AddObserver, which is
fundamental to my application.

Any ideas how to go on? I saw a few related threads, none concluded.
