Comment (by strk):

 Here's a simplified testcase:
 {{{
 SELECT createtopology('invalid');

 SELECT count(*) from (
   SELECT TopoGeo_addLineString('invalid',
 'LINESTRING(
   12.123711265448206 65.12785021295713,
   12.123711265448206 65.21007378815003,

 '
   )
 ) foo;

 SELECT * from validatetopology('invalid');

 SELECT count(*) from (
