dbus help needed in sending an a{sv}

[M_o_n_k_e_y]

For a nabble is hard to understand using d-bus, there is many libraries and
few documentation. I am trying to use lowlevel API (
http://dbus.freedesktop.org/doc/dbus/libdbus-tutorial.html Lowlevel API ).
I wrote the code under but don't work.
When arrive at "dbus_pending_call_block(pending)" application block to
infinity loop.
Any suggestion will be appreciated

dbus_bus_get(DBUS_BUS_SESSION, &err);
...
// request a name on the bus  
ret = dbus_bus_request_name(conn, "org.freesmartphone.opimd",
         DBUS_NAME_FLAG_REPLACE_EXISTING                    
         , &err);
