The panic is in line 67, when you were decrypting the private key. However you provided a public key (see line 131).
These things are always obvious to a fresh pair of eyes :-) In short, you need to provide *Roger's public key* and *Roger's private key* respectively. The public key is used to encrypt the message, and the corresponding private key is used to decrypt the message. Alice's key is *not needed at all*.
