Didn't Charl post a patch for this (for Python wrappers) a long while
ago? Here is the thread:
Reading that I see that the patch changed quite a bit before anything
was checked in.
Does VTK generate exceptions now? I've fallen a lot behind on VTK
from CVS and been mainly using VTK-4.4. I don't recall discussions
about VTK generating exceptions?

If VTK objects will generate exceptions then we should really fix the
Python wrappers as well.
I've also been thinking about adding support for weakly referencing
VTK-Python objects. Does anyone have objections to this?
