I would say it relates with prohibiting shipyards on some map. The code here:
http://bazaar.launchpad.net/~widelands-dev/widelands/trunk/view/head:/src/map_io/map_saver.cc#L145
implies that if there is building that is not allowed encountered, list of allowed buildings are put into map. Or into savegame perhaps too.
Tribe cannot be changed in game, but in editor it can be.
