82cbfecb - virtual buffer selection property: It is possible for a VirtualBufferTextInfo's NVDAObjectAtStart property to return None; i.e. the object with the ID supplied by the buffer couldn't be retrieved. I don't understand why this happens, but if it does, deal with it gracefully - just don't try to scroll or set focus to it, rather than throwing an exception and causing the whole operation to fail. May fix #222. Alternatively, it might just hide a deeper problem. :)
