Hmmm, I see there is a bug in the placement of the gravatar when the read view display is set to flat. If you don't want to wait while I fix that, you could change the Gravatar module settings to not automatically display the gravatar image on the read views (controlled by the setting "Turn on gravatar autoinsert for: Message reading" in the module's admin settings page). In the meantime, you could still have gravatars displayed in the read view template by inserting the code yourself, which is described in the readme.
I will post a fix as soon as I can.
