Actually, this warning is just a warning, and not a critical error that will 
stop conversion. When this occurs, the way/relation will be skipped. Due to 
the way the OSM database is done, it is possible to have non-valid polygons, 
and indeed there are such polygons.
So you can safely ignore those warnings about organizePolygons()
