Comment:

 Okay so with the index, no fail.

 And when drop index


 {{{
 DROP INDEX test_table_lines_geom_idx;

 SELECT *
 FROM test_table_lines t
 WHERE st_dwithin(st_setsrid(ST_GeomFromText('MULTILINESTRING EMPTY'), 0),
 t.geom, 1);
 }}}

 Bam fail with:


 {{{
 ERROR:  LWGEOM_dwithin: Operation on mixed SRID geometries
 (MultiLineString, 0) != (LineString, 27700)
 SQL state: XX000
 }}}

 That said yes it's a regression and the behavior is not the same. That
 said is this something we can even fix even if we cared to fix it without
 some dier consequences?  I think the answer is NO.

 So marking this as a won't fix.
