You should complain :-) Logging fake ids does not help anyone to have a 
look on the OSM data. The warnings you see indicate wrong OSM data (an 
inner way intersects an outer way) OR it indicates problems with the 
tiles. In any case one must have the chance to check that.

That's great. I will grab it now and check it tomorrow.
I suppose that the problem is the autoclosing mechanism. The new 
multipolygon code tries to close ways by just readding the first point.
I think I must add a bounding box check (if first and last point of an 
unclosed polygon touches the bounding box then the polygon is 
complemented by the bounding box - otherwise the simple algorithm is taken)
