ST_Segmentize returns invalid LINESTRING for zero-length input

[realityexists]

PostGIS 2.0.0 as of 2011-11-08

SELECT ST_AsText(ST_Segmentize(ST_GeomFromText('LINESTRING(1 2,1 2)'), 100))

returns "LINESTRING(1 2)", which is invalid - parsing it with ST_GeomFromText() fails. I would expect it to return the input value ("LINESTRING(1 2,1 2)").
