Comment(by strk):

 Oddly enough, interrupting the insertion of edges on error and querying
 the database I find 2 candidate points but both seem to be pretty far from
 each-other:

 {{{
 =# with p as ( select
 '0101000000B0B7BE9F8369294180870580ACEA2841'::geometry g ) select node_id,
 st_distance(geom, p.g) from small_sample_topo.node, p where geom && p.g;
  node_id |     st_distance
 ---------+----------------------
     2515 | 3.97360129963356e-08
     2516 | 0.000998956812181611
 (2 rows)
 }}}

 Now to figure out how did that point move... (hoping ST_Distance is _not_
 using bounding box)
