I just checked with the VolumeRenderWithBoxWidget.py example and
modified the EndInteractionEvent to perform a VTK action that
generates an exception. The application simply continues when this
happens, as expected.
The code simply results in a Python exception, not a C++-exception.
Python exceptions in general don't result in application exit if
they're not explicitly handled, AFAICR.
Also remember that the old behaviour can be reinstated with:
ow = vtk.vtkOutputWindow()
So far, I haven't been able to think of any serious drawbacks to this
