Version: 4.6 (using KDE 4.6.2)
OS: Linux

With openssh version 5.8, ssh keys of type ECDSA have been implemented.
When I first connect to an SSH server with ECDSA public keys, this key is added to known_hosts, and consequently it must be verified in all subsequent connections.

KDE's KIO_SFTP fails to verify such keys, while the ssh command line program works perfectly.

The workaround is to add a different ssh host key to the known_hosts file. This could be achieved by making the first connection to the SSH server specifying a different host key algorithm:
$> ssh -o HostKeyAlgorithms=ssh-rsa root@host

After doing this, everything works as expected.

Reproducible: Always

Steps to Reproduce:
1. Connect for the first time to a SSH server with openssh version >= 5.8.
2. Copy a file with the sftp kio slave:
  $> kioclient copy sftp://HOST:test.txt .

Actual Results:
Host key fails verification

Expected Results:
The file should be copied from the remote server
