[OSM-talk] Mapnik: strange prioritisation/appearance of place names

It likely clashed with the airport icon on this zoom level.

What you perhaps want is a rule that draw the "most important" cities 
before it draws any icons or highway shields that might later cause 
labels to be dropped. This is not so easy however due to the varying 
definition of "most important", especially in a tiled environment. 
Perhaps it is possible to do something like "draw n most populous 
cities, then the rest" or so.
