Is your username on the client side also "lucio"?  If so, those should 
be literally identical in terms of what the server sees ...

Could I please get the output of both "ssh -vvv localhost" (in a case 
where it works) and "ssh -vvv lucio@localhost" (in a case where it 
crashes)?  Also whatever server logs you can find.
