Fixed. I was basing source location off of a fully qualified name of the type. Most of the time, this does not have any effect, except when the content assist invocation location is shorter than the length of the fully qualified name.

Now, I am being more careful to appropriately pick the qualified or unqualified name to base content assist on.
