     Type:  defect   |      Status:  new          
 Priority:  medium   |   Milestone:  PostGIS 2.0.0
Component:  postgis  |     Version:  trunk

Comment(by strk):

 Gah, it has to do with $1 ~= $2 !!!
 Both are affected because both insist in requiring bounding box overlap
 for two geometries to be equal. Does the EMPTY bounding box overlap the
 EMPTY bounding box ?

 Do voids touch ?
