A simple dbus application:
- do a connection to system bus;
- call method ListNames of org.freedesktop.DBus service;
- print list of services;
- exit;

In this case on my application i do:
- dbus_bus_get (system bus)
- dbus_bus_request_name;
- ... do method call
- dbus_connection_unref()
- dbus_shutdown
- exit

On session bus this works fine, on system bus 
before exit an abort is handled for:
 dbus_shutdown() called but connections were still live. This probably
means the application did not drop all its references to bus
connections.

So, i can't shutdown on system bus.
