I just replied to this, with a solution. Next time, please keep the email
headers intact, including the subject line, unless you are actually changing
the topic. Those of us who consume mailing lists in conversation format
appreciate it.

I will point out however, that you should wait to use is_user_logged_in()
until the init hook. Or simply throw is_user_logged_in() into the callback
and short-circuit the filter if you don't need to process anything.
