Comment:

 I've taken the liberty to paste Martin's
 [http://lists.osgeo.org/pipermail/geos-devel/2009-March/003950.html
 comment posted on the list]:

  ''This is an error in JTS as well.  EMPTY components are generally not
 handled. The whole idea of having empty components seems pretty pointless
 to me anyway. I suppose the best thing to do is to simply strip them out
 in geometry operations.''

 I believe we can leave the ticket open to not to forget in future, but
 with clear statement that users are advised to strip EMPTY components out
 from their geometries.
