Comment 2 for bug 368204

Yes, tried that. I think the config must be changed because it looks like a documented feature.
See man dbus-daemon, the section about policies:

       Policies are applied to a connection as follows:
          - all context="default" policies are applied
          - all group="connection’s user’s group" policies are applied
            in undefined order
          - all user="connection’s auth user" policies are applied
            in undefined order
          - all at_console="true" policies are applied
          - all at_console="false" policies are applied
          - all context="mandatory" policies are applied

       Policies applied later will override those applied earlier, when the
       policies overlap. Multiple policies with the same user/group/context
       are applied in the order they appear in the config file.

Looked to me like the at_console policy denies the sending of the messages, because
it is applied after the user = root policy. In the logs one could clearly see, that there were messages
denied due to some config rules.
