 Priority:  medium   |   Milestone:  PostGIS 2.0.2
Component:  postgis  |     Version:  2.0.x

 This doesn't help analisys:
 {{{
 strk=# select 'POINT EMPTY'::geometry = 'POINT(1 1)'::geometry;
  ?column?
 ----------
  f
 (1 row)

 strk=# select 'POINT EMPTY'::geometry = 'POINT(0 0)'::geometry;
  ?column?
 ----------
  t
 (1 row)
 }}}

 I suspect it has to do with bounding box of EMPTY being arbitrarily taken
 as 0,0,0,0
