I already have

<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-BUS Bus Configuration 1.0//EN"
 "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd">
<busconfig>
  <policy user="bin">
    <allow eavesdrop="true"/>
  </policy>
</busconfig>

in /etc/dbus-1/system-local.conf. Should I try to add it to some other
file?
