Ah yes, that was my other question: you refer to processed_a, but I
can't find a file of that name. Where did you get it?

The ABA polygons are expected, since mapnik can render them (you get a
line). The nested polygon shouldn't happen and ring-self intersections
shouldn't happen anywhere where the coastline doesn't show errors...

Have a nice day,
