Btw Christoph,
If you have multiple shortest path routes to figure out (as in hundreds, millions, or billions in my case), contact me. I am working on a python script to do that.

> Multipart to Singlepart
> Check validity (use both methods)
> Remove duplicate vertices
> Deleted duplicate geometries
> Snap geometries to layer, (search for snap in processing)
> V.clean (break an snap,rmdangles....) see the cleaning tools.
