I'll be moving this to the JFBConnect forums after I post this, just so you know to look there..
That's definitely strange, and not something we've heard of before. What if you go just to
developers.facebook.com/ ? If you were logged into Facebook and using the "Use Facebook As" feature to act as though you're a Facebook Page, I can see where something strange like that may happen. You can only create apps using 'people' profiles, not Pages.. If you're going to your home page even when you're logged out, thats' just odd.
Can you try from a different computer or Facebook account and see what happens?
Thanks,
Alex
