Both these have 2 ways which together could form a closed ring if the direction of one of the ways was reversed. I think these were marked as multipolygons by the 0.4->0.5 conversion script since it could not form a closed ring with the directions as they were. I think we need to fix up these into proper closed ways and remove the multipolygon relation.
Given your stats above this might effect about half the existing multipolygon relations. It just so happens that the existing multipolygon handling code in osm2pgsql will convert these ways into a closed area for the Mapnik rendering. I can not remember whether this was by accident or design but it would be nice not to lose these areas.
