Hi, another hint: if I remove all the srs from the mapfile, the tiles are generated CORRECTLY while Dane said that the result should be something screwy... The only thing that doesn't work here are the scale based rules. I think that Mapnik ignore what the measure unit is, so it cannot calculate the scale correctly. Maybe introducing a unit="..." param for the map should be a good thing?
