Maybe it  could happen, if there is very much sea in a tile. This is my 
largest sea-tile: 2772992,-1259520 to 3336192,71680 (Garmin-units) and 
it works without problems. Maybe it depends on memory.

So there are two solutions: generate it with --no-trim and manually 
tweak in area.list some tiles or tweak many sea-tiles with holes. I 
would prefer the first one ;-)
