It appears that it is possible unclosed polygons are parsed in the shapefile plugin. This leads to completely painted maps, whereby the shapefile fill color acts as if it were the background.

I think this is a regression after the `geometry_cleanup` work. This exhibited in tilemill as disappearing features at z18, for reasons that are unclear (z0-z17 look normal and only polygons are filled).
