I think this option still needs to be refined. I have downloaded  
coastline extracts and specially processed them (for a separate sea  
layer), and have had similar problems. The data I was working on did  
not need to be split, so I think you can rule the splitter out as  
being part of the problem.

It seems that under certain circumstances the generate-sea option  
inverts land and sea.

Cheers.
