I use multiple ssh keys and have a .ssh/config to ensure the correct keys are used for each address. On the command line everything works fine, but whenever I try and connect to my local server using the kio-sftp plugin in Dolphin or the KNetAttach wizard to add a a ssh folder, it fails with a "can't connect to server" error message (KNetAttach) or "The host key for this server was not found, but another type of key exists (sftp:// url in dolphin)."

Reproducible: Always

Steps to Reproduce:
1. Create a .ssh/config with an identityFile specified other then the default id_rsa
    i.e. Host foo
              IdentityFile ~/.ssh/foo
2. Open dolphin and enter that servers address using the "sftp://" protocol
    i.e. sftp://foo
Actual Results:  
"The host key for this server was not found, but another type of key exists" error message will be displayed.

Expected Results:  
Either a password dialog if the ssh key was password protected or it should just display the contents of the remote system specified in the sftp://foo/<path> url.
