<p>Just jogged my memory a bit and retested on my instance.</p>

<p>The check if a gravatar is available or not takes place when the user uses the link from the confirmation mail, that in itseld shows a notice that the e.mail has been changed. I suspect a work around would be to merge the messages / create two additional ones for the case when the gravatar enables status has changed.</p>
