Comment (by strk):

 Figured finally: problem is that we're ONLY scrolling the intersection
 between the new line and the existing linework, leaving out any NEW
 portions. Here's the smalles repro:
 {{{
 SELECT NULL FROM CreateTopology('b5081');
 SELECT 'b5081.0', 'E' || TopoGeo_addLinestring('b5081', $$
   LINESTRING(0 0, 10 10,10 -10,0 0)
 $$);

 SELECT 'b5081.1', 'edges', count(*) FROM (
   SELECT TopoGeo_addLinestring('b5081', $$
     LINESTRING(
       -10 0,
       0 0, 10 10,10 -10,0 0,
       -10 0
     )
   $$)
 ) foo;
 }}}

 I'm surprised this doesn't show up more often.
