please insert a commitChanges() call here. The bounding volume is
updated lazily when modifying the scenegraph (they are invalidated
immediately, but the recomputation is lazy).
Since this has come up before we should probably insert the call at the
end of loading, I'll take care of that.

hm, I have no idea why only the debug libs are affected, but it may be a
coincidence that the release libs give the expected answer.
