Bastien I have found the problem. Unfortunately there is nothing that you or I can do to fix the situation, and we must wait for the OSM system admins.
The problem is that prior to 14 December 2011 some ways in the area near Cienaga San Silvestre were tagged with natural = coastline. I can not be sure of the exact cause of the problem, but there was an error in these ways which then caused a problem in the files used to create the coastline in the mapnik layer (http://tile.openstreetmap.org/processed_p.tar.bz2) . (This file is used to generate shapefiles of the coastline, the shapefiles contain 100km x 100km polygons of coastline data, and unfortunately the error affected two of these polygons so there is an affected area of 200km x 100km) This file is not updated by the system admins very often , and the current file in use is dated 9 December 2011, so it is earlier than the changes I made on 14 December 2011. Although I corrected the error on 14 December the effect of this will not be seen on the mapnik layer until the sys admins update the coastline shapefiles. ( Note there are other areas of the world which also have errors http://www.openstreetmap.org/?lat=-17.59&lon=-72.28&zoom=8&layers=M http://www.openstreetmap.org/?lat=57.567&lon=-3.877&zoom=10&layers=M). I hope this helps explain the problem. If you need further help then please contact me.
