GetError won't tell you why something is Invalid. If it is invalid, it will
just return a default constructed SBError, which has nothing useful in it.
What I intended was: my code is asking GetType, GetError, etc of an SBValue and
everything it gets back is just an empty default-constructed return. If you
want to know why that might be, check IsValid, and if it's false, that's why.
