This is not a Routino bug, it is a bug in the Openstreetmap data that
Routino is using.

The road that has been selected for the start point is marked as
one-way and is a dead-end.  If you follow the road (in the only
direction allowed) you will come to the end where you can go no
further.

You can see this more easily in this zoomed in map:

http://www.openstreetmap.org/#map=18/51.45887/-0.44572

Routino cannot calculate a route where there is no viable road.


It could be argued that Routino should remove one-way highways that
lead into a dead-end and one-way highways that start from a dead-end
but that is a feature request, not a bug.  Routino does make efforts
to remove highways that cannot be used for routing but one-way
highways like this are not included.
