null proxy0 in ConvexResultCallback::needsCollision ?!

[TheChuckster]

For raycasting, what would cause the proxy0 argument in ConvexResultCallback::needsCollision to be null?

My app was crashing whenever I walked into a certain room in my environment.

I added a null check, and it resolved the crashing issue (return false if proxy0 null).

Any ideas? Perhaps I overlooked something that needed to be set up?
