Comment(by pramsey):

 And looks like any simple version with just two duped coordinates will do.
 However duped coordinates in a larger line have no problems:
 {{{
 -- works
 select _st_distancetree('LINESTRING(0.1 0,0 0,0 0)'::geography, 'POINT(0.1
 0.1)'::geography);
 -- works
 select _st_distancetree('LINESTRING(0 0,0 0,0 0.1)'::geography, 'POINT(0.1
 0.1)'::geography);
 -- boom
 select _st_distancetree('LINESTRING(0 0,0 0)'::geography, 'POINT(0.1
 0.1)'::geography);
 }}}
