I didn't quite forget, rather in refactoring all the Vec, Quat and
Plane code I missed adding Quat and Plane support to two places where
it was missing previously. Looking at your original submission I now
see you added in Quat handling as well as the Vec, but once I had
started down the path of refator I didn't refer to again as I thought
I had the idea of what you were trying to achieve.
I've just checked in the missing Quat and Plane handling. Fingers
crossed this is all the cases handled now.

Looking at the original code it looks like you've added the
dynamic_cast<const osg::Object*>. I'm surprised this is needed as
the getting should be returning a Callback pointer of some kind which
should already be an osg::Object. If this is crashing then I can only
guess there is an issue with the virtual inheritance somewhere along
the line.
Could you post a .lua script that reproduces the crash?
Robert.
