I'm unsure how that happens, but deegree for example always sends a
service exception in case minx == maxx or miny == maxy, and we pass
the tests. However, your service advertises the mentioned request box
as the layer's bounding box, the scripts probably just try to request
the layer with its advertised bounding box.
