I don't see it anymore.
First of all, I think we'd all agree that funny bugs like this are WAY better than game-breakers. X-D
@crinrict: I read in a comments section over at Carl's Sims Guide from someone whose baby was born a B-Lister. Judging from your post, though, it'll only be temporary. I wonder if your thing with the baby losing fame on Aging Up is because babies are technically objects by the game code's standards, and everything else mentioned is an object. (Actually useful part of this post, hence the Boldface. ;-P)
And yes, famous Patchy, please! He could star in a remake of The Wizard of Oz. 😃 ("♪ If I only had a brain... ♪")
The same thing happens to the scarecrow when he is at the tree. When he is alive, he is normal. A little funny bug actually.
