Send an Email activity fails with Tokens

The Contact "Send an Email" activity fails when

{action.unsubscribeUrl} {action.optOutUrl} {domain.address} tokens are included in the message body. The error also occurs when including {action.unsubscribe} {action.optOut} {domain.address} tokens.

Here is the html code I've used successfully in CiviMail 4.1 templates:
<p>To stop this newsletter <a href="{action.unsubscribeUrl}

" target="_blank">Unsubscribe</a></p>
<p>To block all email <a href="

{action.optOutUrl}

" target="_blank">Opt-Out</a></p>
<p>This email is from:<br /><span style="font-size: 80%;">

{domain.address}

</span></p>

And finally, from the error log:
