Buffers menu item doesn't list all open buffers

Binary package hint: emacs22

1. Open a file in emacs
2. Open a second file
3. Open a third file
4. Click "Buffers" in the menu

Only the first opened file displays in the list (along with scratch and messages).

I believe this is controlled by the "Buffers Menu Max Size" setting, which is currently set to 10, so it should be displaying more than just one, but isn't.
