Option 1: Fix them Option 2: Provide a list so someone else can fix them Option 3: Provide an example so I can look and see if there's an easy way to detect them Seriously though, it's probably a bug that should be fixed. The tools are there, mostly we just don't know how to use them. For example, while writing the coastline checker I found that libshp has a RewindObject function which takes a polygon and fixes all the rings. Neither my program nor mapnik cared either way, but other products may not be so lucky. FWIW, self-intersecting polygons generally don't render well, so some examples would give an idea of what to look for.
