hi, all
     I'm a beginner on gstreamer.
I add some gstreamer code to play sound in RedOffice(Openoffice.org) using gstreamer, but, at some times the RedOffice program will has not any response for input when it finish the sound playing, the RedOffice must be killed and restart it.This computer is MIPS, linux debian 2.6.27.1, has install gstreamer0.10-plugins-base, and gstreamer0.10-plugins-good.
But the bug doesn't exist on other computer(MIPS, linux debian 2.6.18.1, has also install gstreamer0.10-plugins-base, and gstreamer0.10-plugins-good).
Is anybody know the reason? It puzzles me a long time.
THX.

ps:
  following is some code, attachment is the whole source code:

void SAL_CALL Player::start(  )
    throw (uno::RuntimeException)
{
    //OSL_TRACE ("Player::start");
    // set the pipeline state to READY and run the loop
    if( mbInitialized && NULL != mpPlaybin )
    {
        gst_element_set_state( mpPlaybin, GST_STATE_PLAYING );
    }
}

void SAL_CALL Player::stop(  )
    throw (uno::RuntimeException)
{
    // set the pipeline in PAUSED STATE
    if( mpPlaybin )
        gst_element_set_state( mpPlaybin, GST_STATE_PAUSED );
}


bool Player::create( const ::rtl::OUString& rURL )
{
    bool    bRet = false;
    // create all the elements and link them
    if( mbInitialized )
    {
        GstBus *pBus;
        mpPlaybin = gst_element_factory_make( "playbin", "player" );
        rtl::OString ascURL = OUStringToOString( rURL, RTL_TEXTENCODING_ASCII_US );
        g_object_set( G_OBJECT( mpPlaybin ), "uri", ascURL.getStr() , NULL );
        pBus = gst_element_get_bus( mpPlaybin );
        gst_bus_add_watch( pBus, gst_pipeline_bus_callback, this );
        gst_bus_set_sync_handler( pBus, gst_pipeline_bus_sync_handler, this );
        g_object_unref( pBus );
        gst_element_set_state( mpPlaybin, GST_STATE_PAUSED );
        bRet = true;
    }
    if( bRet )
        maURL = rURL;
    else
        maURL = ::rtl::OUString();
    return bRet;
}
