Comment(by strk):

 Can you provide HEXWKB please ? It's what you get by default if you
 `SELECT the_geom FROM table` from a text cursor. I don't need the utmzone
 function, just the original and simplified geometries.

 The idea is to produce a testcase that would trigger the bug in a script
 like this:

 {{{
  SELECT CreateTopology('bug2176');
  SELECT TopoGeo_addLinestring('bug2176', '<first_geometry>');
  SELECT ST_ChangeEdgeGeom('bug2176', 1, '<second_geometry>');
 }}}

 With the smallest possible '<first_geometry>' and '<second_geometry>'
