FWIW, whenever I encounter a natural=coastline that should not be so, I 
will either add the polygon to a multipolygon relation and remove the 
natural=coastline tag (so that only the multipolygon relation will carry 
area-defining tags), or replace the natural=coastline with 
natural=water.  I guess that some Potlatch users do not know the 
difference between water and coastline.

The relation 96565 looks bogus to me. The name and natural=* tags should 
be on the relation, not on the outer way. If the natural=coastline is on 
the role=outer line (Randsfjorden (8758490)) then mkgmap is entitled to 
flood the tile. :-)
