If you run the script manually, you should see the errors, it used to 
complain about a man-in-the-middle attack, presumably called Malcolm :)

In your ~/.ssh or ~/.ssh2 directory, you should find a file called 
known_hosts - zap the entry from there for the host (on the sending 
side) - you may also need to initiate another transfer to confirm you 
trust the new key.
