software-center crashed with TypeError in _create_dbus_sso_if_needed(): __init__() takes exactly 4 arguments (2 given)

Binary package hint: software-center

When I clic on "Fichier > Réinitialiser les achats précédents..." (French version of Ubuntu), this error appears.
I use Ubuntu 11.04 bêta, installed since Ubuntu 10.10 (distro upgrade).

(apt-cache policy software-center)
software-center:
