Could you give a link to a suitable position to see this on the map?

One possibility is that this way is the border of multiple regions and
has a tag like:
	admin_level="7;8"

If so, this causes problems for the older osm2pgsql/mapnik code which
running on the tile server at the moment. I plan to update to the trunk
osm2pgsql code which should handle this better.

A trac ticket does make it easier to keep a record of known issues.
