Comment (by strk):

 Ok I've handled to write a regress test. Now to decide what to do about
 the situation. The situation is that the topology is corrupted in that you
 cannot build an area using edges that are tagged to take part of a face
 (cannot build face geometry).

 Returning an empty set from ST_GetFaceEdges sounds wrong to me, because
 edges _tagged_ to be part of the face do exist, only they cannot be
 ordered around the ring because no ring is formed. For this reason I'd
 raise a Corrupted Topology exception in this case.
