I think this is just bad data: As far as I know, the splitter doesn't  
create new osm ids, and if you look at those ways (e.g. http://www.openstreetmap.org/browse/way/35170062) 
  you'll see that those existed but have been deleted. Is it possible  
that your germany.osm.bz2 was from a different time than  
problem.osm.bz2?

If not, maybe there's a bug somewhere (splitter?) that undeletes  
elements with visible='no', and your source data contained the deleted  
ways?
