ok, tried this too and i did not succeed into having it to work.
the code is:


void add_sine(){
         GstElement *tsine;
         int pstate;
         GstPad *newpad;
         GstPad *toblock;

         tsine = get_silence_bin();
         gst_bin_add(GST_BIN(pipeline), tsine);


         //toblock = gst_ghost_pad_get_target(
         //      gst_element_get_static_pad(adderbin, "sink0"));
         //gst_pad_set_blocked(toblock, TRUE);

         newpad = gst_ghost_pad_new("sink1",
                 gst_element_get_request_pad(adder, "sink%d"));

         gst_element_add_pad(adderbin, newpad);

         gst_pad_link(gst_element_get_static_pad(tsine, "src"),
                 gst_element_get_static_pad(adderbin, "sink1"));

         gst_element_set_state(tsine, GST_STATE_PLAYING);
         //gst_pad_set_blocked(toblock, FALSE);
}

yes, i have g_thread_init(NULL) call and gst_init() for first in the  
main (and i think that gst_init() does a conditional call to  
g_thread_init() when !g_thread_supported(), or am i wrong?

anyway, thanks for your help, i am sorry to bother the list with so  
many mails.
