Playbin with alsasink element as audiosink

[ateixidor]

Hello,

I have a question. I use playbin element to play some files using the
alsasink element into audiosink propierty. The application must run over
long time, but i noticed that the application stops some time after i
started it.

With the GST_DEBUG=playbin:4 variable set, the message that appears is the
next: 

0:18:35.369733877 23457   0x1bbb20 ERROR                playbin

Segmentation fault

i've checked the memory usage with valgrind but i didn't find what could be
the problem.

Here is the code that i use:

        GMainLoop *main_loop; 
	GstElement *pipeline = gst_element_factory_make("playbin", "player");
	GstElement *el = gst_element_factory_make ("alsasink", "alsasink");
	g_object_set (el,"device", "dsp_left",NULL);
	g_object_set(G_OBJECT(pipeline), "uri",
"file:///mnt/jffs2/msg/espancomido.ogg", NULL);
	g_object_set(G_OBJECT(pipeline), "audio-sink", el, NULL);

	main_loop = g_main_loop_new (NULL, FALSE);
	
        GstBus *bus;
	bus = gst_element_get_bus (pipeline);
			 
	gst_bus_add_watch (bus, (GstBusFunc)handle_message, main_loop);
	gst_object_unref (bus);
		
	gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_PLAYING);
	
	g_main_loop_run (main_loop);
			
	gst_element_set_state(GST_ELEMENT(pipeline), GST_STATE_NULL);
	g_main_loop_unref (main_loop);
        gst_object_unref(GST_OBJECT(pipeline));

Coult anyone tell me if i'm doing something wrong?

Thank you very much.
