Comment(by robe):

 to add to this - ST_AsKML geography variant appears to crash for ALL
 variants of EMPTY. Including our beloved GEOMETRYCOLLECTION EMPTY.

 SELECT ST_AsKML(geography(ST_GeomFromText('GEOMETRYCOLLECTION
 EMPTY',4326)));

 and the geometry empty variants is returning NULL:

 {{{
 SELECT ST_AsKML(foo1.the_geom) is null
 FROM ((SELECT ST_GeomFromText('POINT EMPTY',4326) As the_geom
         UNION ALL SELECT ST_GeomFromText('MULTIPOINT EMPTY',4326) As
 the_geom
         UNION ALL SELECT ST_GeomFromText('MULTIPOLYGON EMPTY',4326) As
 the_geom
         UNION ALL SELECT ST_GeomFromText('LINESTRING EMPTY',4326) As
 the_geom
         UNION ALL SELECT ST_GeomFromText('MULTILINESTRING EMPTY',4326) As
 the_geom ) ) As foo1 ;
 }}}
