Well if you have a screwed up ssh server that refuses connection like I do 
right now, then kio_sftp with your changes SEGFAULTS and I think I know why... 
There is a code that does the following in openConnection:

  sftp_session = sftp_new(ssh_session);
  if (sftp_session == NULL) {
    closeConnection();
    return;
  }

but unfortunately, closeConnection also does...

  sftp_free(sftp_session);
  sftp_session = NULL;

so if sftp_session is already NULL as in the above case, then the ioslave goes 
down in flames. Once I get around to fixing my ssh server, I will test basic 
functionality and let you know, but I think it should be fine to commit this 
into the main tree on work on improving it from there, no ?
