I can confirm the bug on Hardy intel 32bits, up to date and using the "proposed" repositories.
In my case the affected symptom is a few applets (most notably the trash icon) disappearing from panels. The problem persists even after several reboots. But, if I manually kill bonobo-activation-server and then restart the panels (killall gnome-panel) the affected applets are displayed again.
