problem with turn restriction

Could someone please check, why this turn restriction ( http://www.openstreetmap.org/browse/relation/1185721 ) produces an error in the OSM restriction analyser ( http://osm.virtuelle-loipe.de/restrictions/?zoom=18&lat=50.07739&lon=8.2452&layers=B00TT )? The error is: “to-way segment with no length”.

Greetings!

There was something wrong with this way, it seemed to have the same node in it multiple times. See the history: http://www.openstreetmap.org/browse/way/4086920/history
I’m not sure what caused this, but I think I’ve fixed this now. The restriction analyser shows it OK.

Thanks!

ALE!
