Comment(by amartin):

 The behavior can be reproduced with only two components

 {{{
 SELECT TopoGeo_AddLineString('my_topo',indiv_geom, 0.8)
 FROM (SELECT (ST_Dump(p_geom)).geom as indiv_geom
  FROM (SELECT ST_GeomFromText('MULTILINESTRING ((535695.149659

 geom_squery) AS lines;
 }}}

 Still getting duplicate edge_ids and a newly created edge_id is unreported

 Query result:
 {{{
 "topogeo_addlinestring"
 "50"
 "52"
 "50"
 }}}

 my_topo.edge_data table:
 {{{
 edge_id
 50
 51
 52
 }}}
