How to free ressources allocated by dbus_bus_get ?

[10function]

Hi Guyz,

I was wondering how memory ressources claimed by 'dbus_bus_get' should be released.
I used 'dbus_connection_unref' and 'dbus_connection_close' calls, but memory leaks are always present.

Here's the sample/simple program i used:
#define DBUS_API_SUBJECT_TO_CHANGE
#include <dbus/dbus.h>

int main()
{
 DBusError err;
 DBusConnection* conn = dbus_bus_get(DBUS_BUS_SYSTEM, &err);
 dbus_connection_unref(conn); /* check with dbus_connection_close also */
 return(0);
}

And the valgrind/memchecks complains :

Thanks for your gurus eyes ...
