Thanks for the link Silke. As I got a better look at the world_borders
and your data I found what the problem was with the weird rendering. The
error was all mine and had nothing to do with the actual data. It was
due to the proper SRS value being overwritten by a wrong one, which
naturally caused the problem. All is fine now.

Kai
