I suppose the fix wasn't yet in the mirrors because I got the problem a few minutes ago. I've worked around it by deactivating at-spi (gnome-at-properties). I suppose at-spi was conflicting somewhere with update-manager. I thought I would share my finding with the community and I found this bug which was solved 10 hours ago.
