Error org.freedesktop.DBus.Error.TimedOut: Activation of org.freedesktop.PackageKit timed out

[Martin-Éric Racine]

Whenever (re)installing Packagekit, I keep on getting the following:

Setting up packagekit (0.7.1-1) ...
Error org.freedesktop.DBus.Error.TimedOut: Activation of org.freedesktop.PackageKit timed out

Sure enough, during normal utilization, a similar error appears, such as when running "apt-get update":

Error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

Dbus runs as expected for other applications, so I suspect that this newer Precise packagekit version is to blame, since everything works fine on my Oneiric hosts.
