I can't replicate this with CVS -current, either in inet or normal mode.
Please
reopen if you can.

The problem still exists in 3.6.1, but upon rereading what I posted,
I see I didn't describe the problem accurately.
The problem occurs when running sshd with the -i option with both
protocol 1 and protocol 2 enabled. If someone connects using protocol
2, the protocol 1 ephemeral key is still generated. You can see this
by running sshd with the -ddd option.
The ephemeral key generation is skipped if protocol 1 is disabled.
But when the -i option is used even if protocol 1 is enabled if the
current connection uses protocol 2 the generated ephemeral key will
never be used. Hence not generating it under those conditions seems
like a good idea.
