ospf stub interfaces appears as two entries in routing table (direct + ospf)

[Kenth Eriksson]

If I configure an OSPF interface as a stub interface, why does it appear twice 
the routing table? E.g. setting interface lo as stub interface results in the 
following;

10.210.137.78/32     unicast [direct1 15:59:09.550] * (255)
        dev lo
                     unicast [ospfv2_1 20:47:56.864] I (145/0) [10.210.137.78]
        dev lo

The source OSPF-I misleads me in thinking that it was learned from the OSPF 
area.
