Comment(by strk):

 Uhm, I was wrong, lwcollection_construct is really talking about ZM flags.
 Some components of the result have a Z and some others don't.
 Could be a GEOS bug (intersection returning a collection of items with
 mixed coordinate dimensions).

 Do your polygons or lines or both have a 3rd dimension ?
 Is the problem "fixed" by forcing them to 2d only ?
