  * summary:  ST_CollectionExtract not Empty safe => lwgeom_free not empty
              safe

Comment:

 In fact, the problem is a little deeper. Hard to believe we don't do this
 in other places, but it seems to be a generic problem with freeing
 empties, or more to the point, that the lwgeom's returned by
 pglwgeom_deserialize aren't constructed in such a way we can free them
 safely. More investigation req'd.
