I have experienced this behaviour too ... the Panels are hidden by default when added. That's why they appear when logging out and in. This is fixed in the next version of gnome, 2.31.2, I think, because the gnome panel news contains an entry: "Make sure that newly-created panels become unhidden (Vincent)"
