Short description of error
Lamp objects don't display bounding box
Exact steps for others to reproduce the error
Working in the attached file when using any lamp object (and more specifically the "area" variant), the bounding box that indicates the size of the light source does not show. Basically all lamp objects show as if they were a point or a vertex.
