[BLOCKER] [CRASH] latest libbonobo commit crash a lot of applets

[Luca Ferretti <elle uca libero it>]

After updating some modules in my jhbuild test install, gnome-panel
applets and/or nautilus crash on session startup.

It could be related to recent crash-on-g_critical but:
      * `killall nautilus` restarts Nautilus gracefully and it starts to
        work
      * `killall gnome-panel` restarts the panel, loading some applets
        (show-desktop, window-list, wp-switch), but still failing on
        other defaults (mixer, notification-area, clock). The menu-bar
        applet is always loaded.
      * downgrading libbonobo the session starts with no crash
      * nautilus always crash on logout
