[gnome-db] GnomeDB button in Glade disappears after I new a project.

Hello,

I installed glade and gnomedb on my Debian system. When I run the glade, I can see
the GnomeDB button in it's panel. But after I new a project, this button
disappears.
I do not know what is the problem. Could you give some suggestions?
