I do not see anything obviously wrong in the data.  According to the wiki,
Germany uses type=multipolygon relations instead of type=boundary, but
the styles/default/lines should accept both.

The boundary lines around here are similar (relations with multiple admin
levels) and work just fine:
http://www.openstreetmap.org/?lat=60.359479&lon=25.155142&zoom=18&layers=B000FTFT

I added the left:city, right:city on the boundary lines before I learned
that the names naturally belong to relations, not to the boundary lines.
The left:*, right:* rules will not kick in in the default style.

Also the suburban borders in Helsinki obtain correct names from the relations,
as you can see in my Finnish map at http://www.polkupyoraily.net/osm/.
In Hämeenlinna, boundaries are named both by left:suburban, right:suburban
and by relations.  The relations must have been added there some time
this year.

I hope that this helps you further.  By the way, this forum discussion
about misnamed boundaries in mkgmap-generated German maps could be related:
