Comment 8 for bug 1196752

So Powerdevil in KDE is supposed to call systemd-logind now instead of UPower if it finds it. However, it is checking for the systemd version with a call to org.freedesktop.systemd1.Manager.VErsion and not geting a valid response. For some reason, that method doesn't exist on my system.
gdbus introspect --system --dest org.freedesktop.systemd1 --object-path /org/freedesktop/systemd1
node /org/freedesktop/systemd1 {
  interface org.freedesktop.DBus.Properties {
    methods:
      Get(in s interface_name,
          in s property_name,
          out v value);
      GetAll(in s interface_name,
             out a{sv} properties);
      Set(in s interface_name,
          in s property_name,
          in v value);
    signals:
      PropertiesChanged(s interface_name,
                        a{sv} changed_properties,
                        as invalidated_properties);
    properties:
  };
  interface org.freedesktop.DBus.Introspectable {
    methods:
      Introspect(out s xml_data);
    signals:

  interface org.freedesktop.DBus.Peer {

      Ping();
      GetMachineId(out s machine_uuid);

  interface org.freedesktop.systemd1.Manager {
    methods:
