tiles at home has recently switched to using the or/p renderer (instead  
of the original Osmarender) as the default. or/p has a slightly  
different handling of polygons with holes, which was incompatible  
with the output of close-areas.pl (the script used to make polygons  
from coastline sections). I believed I had this fixed, and it worked  
for a number of test cases, but it seems you have found something  
where it doesn't. I will have a look.

Bye
Frederik
