(Gnome, libappindicator) AppIndicator desaparece quando o indicador-application-service é iniciado

Estou usando este exemplo: link no Ubuntu 14.04 [Gnome Classic]. O ícone da bandeja do sistema é exibido. Mas desaparece quando o indicador-aplicativo-serviço é iniciado. Depois que o indicador-aplicativo-serviço é interrompido, o ícone aparece de volta.

Se eu usar o sinal "connection_changed", parece que a propriedade "connected" é verdadeira quando o indicador-application-service está sendo executado, caso contrário - false.

A configuração de APP_INDICATOR_STATUS_PASSIVE enquanto "connected" é true não ajudou (de acordo com: link )

Requisitos:

  1. libappindicator-dev
  2. aplicação do indicador

Passos para reproduzir:

  1. se o indicator-application-service estiver em execução, pare
  2. Exemplo de execução - & gt; ícone é visível
  3. Iniciar o ícone do indicador de serviço de aplicativo - & gt; desapareceu ("Status da conexão: Conectado")
  4. Pare o indicador-application-service - & gt; ícone é visível novamente ("Status da conexão: Desconectado")

Código (exemplo + manipulador de sinal de connection_changed): 

// gcc -Wall app_indicator.c 'pkg-config --libs --cflags gtk+-2.0 appindicator-0.1'
#include <gtk/gtk.h>
#include <libappindicator/app-indicator.h>

void connection_changed(AppIndicator* indicator, gboolean connected, gpointer user_data) {
    g_print ("Connection status: %s\n", connected ? "Connected" : "Disconnected");
}

int main (int argc, char **argv) {
  gtk_init(&argc, &argv);

  GtkWidget *menu;
  GtkWidget *menu_item;
  AppIndicator *indicator;

  menu = gtk_menu_new();

  menu_item = gtk_menu_item_new_with_label("Hello world!");
  gtk_menu_shell_append(GTK_MENU_SHELL(menu), menu_item);

  indicator = app_indicator_new ("example-simple-client",
                                 "indicator-messages",
                                 APP_INDICATOR_CATEGORY_APPLICATION_STATUS);

  g_signal_connect(G_OBJECT(indicator), "connection_changed", G_CALLBACK(connection_changed), 0);

  app_indicator_set_status(indicator, APP_INDICATOR_STATUS_ACTIVE);
  app_indicator_set_attention_icon (indicator, "indicator-messages-new");

  app_indicator_set_menu (indicator, GTK_MENU (menu));

  gtk_widget_show_all(menu);

  gtk_main();
  return 0;
}

Talvez isso possa ajudar:

Se o indicador-aplicativo-serviço não estiver em execução, não há informações sobre esse aplicativo (exemplo-simples-cliente) no log do barramento d (monitor-dbus).

Quando o indicador-aplicativo-serviço está em execução, o log do barramento d contém o seguinte:
