[Bug 30714] Gnome keyboard applet crashes gnome session on AMD64 (breezy)?

Short description changed to:
    On AMD64 breezy gnome-keyboard-applet kills gnome session (at least
    kills gdesklets and affects GTK theme as well).
Description changed to:
    On AMD64, daily updated breezy install started to behave very
    strange (it worked well before). Changing keyboard layout with
    gnome-keyboard-applet does not work any more. If I try to open
    "keyboard preferences" from the menu of the applet and I modify
    something, then strange thing happen: all of GTK applets changes
    widget theme to the default (ugly) one for a second or so, than
    changes back, and some other programs dies (eg gdesklet applets from
    the desktop disappears). Maybe gnome session manager faults (because
    gdesklet is started as "startup programs" tab in gnome-session-
    properties)?

    Maybe it's the same as bug #5124.
