While forcing protocol 2 on the server is not a bad idea, it won't
help here.  Remember, that's a client-side debug message that the
OP was seeing.  I can verify that the client still produces that
message even when talking to a server that does only protocol 2.

Forcing protocol 2 on the client side also does not suppress that
message, so the key-type-determination algorithm is not likely
dependent on the protocol version.
