Luckily (ur unfortunately, since I couldn't reproduce it anymore) I've had this happening only once - but after reading myself into the gconf- structure of the gnome-panel, I saw that there's an incredible mess in the panel configuration itself:
I've played around with those neat panel-drawers before my objects disappeared. It seems that panels leave a lot of orphaned entries in the gconf when adding/filling/removing them. Maybe I managed to create some strange inconsistency in there? -- all panel objects of type != launcher disappeared after drag&drop https://launchpad.net/bugs/75159 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
