It seems that there is a problem if you output two times a routable 
object. I removed the "double ferry" action and at that place it 
compiled fine. It would then crash here however:
http://www.openstreetmap.org/edit?lat=48.50799&lon=13.73188&zoom=17

I did not correct the ferry, but some fool has put highway=cycleway & 
route=ferry on the same way - probably to have autorouting over the 
ferry as he thinks it's part of the Donauradweg. (plus I match of course 
the unroutable cycleway=lane; which has nothing to do on a ferry either).
So this patch will crash if you use continue on route=ferry and 
afterwards have highway=cycleway routable.
