The problem only was that the two env vars
> DBUS_SESSION_BUS_ADDRESS=tcp:host=localhost,port=12434
> DBUS_SYSTEM_BUS_DEFAULT_ADDRESS=tcp:host=localhost,port=12434
were not set. Therefore dbus tries to autolaunch the dbus daemon which
fails because I'm unable to implement _dbus_get_autolaunch_adress().
