Description

Example: 

nibio=# select ST_AsEWKT(toTopoGeom('SRID=4258;LINESTRING(0 0, 10 0)', 'topo_rein_sysdata_rdr', 1, 0));
               st_asewkt               
---------------------------------------
 SRID=4258;MULTILINESTRING((0 0,10 0))
(1 row)

nibio=# select ST_AsEWKT(toTopoGeom('SRID=4258;LINESTRING EMPTY', 'topo_rein_sysdata_rdr', 1, 0));
       st_asewkt       
-----------------------
 MULTILINESTRING EMPTY
(1 row)

Happens at least as back as 2.5.6 (but probably for longer)
