ahh, incomplete data always makes things that much more complicated :-(

I also just got to that admin_level=7. In "Saarland",  one of my test cases,
I see 
"Verbandsgemeinde Waldmohr"
which is the only boundary that has admin_level=7. The interesting thing is:
the returned result-list for this boundary is always empty. So, maybe there
is a cheaper way to detect this first or does it means that there is a bug
in quadtree or the selection of the boundaries?
