title: SWT System Tray - Linux GTK Gnome Tray icons with "SWT" String on tray
body: <p>I am configuring the system tray icons with the following code:</p>
  
  <pre><code>/**
   * Configura os ícones da shell principal
   */
  protected void setDiplayIcons(Shell shell){
      Display display = shell.getDisplay();
      InputStream inputImgTray = getClass().getClassLoader().getResourceAsStream(ImagensNaNOffline.IMG_LOGO_SEBRAE.getPath());
      Image image = new Image(display, inputImgTray);
      shell.setImage(image);
  
      Tray tray = display.getSystemTray();
  
      final ToolTip tip = new ToolTip(shell, SWT.BALLOON | SWT.ICON_INFORMATION);
      tip.setMessage("Balloon Message Goes Here!");
      if(tray != null) {
          TrayItem trayItem = new TrayItem(tray, SWT.NONE);
          trayItem.setImage(image);
          tip.setText("Balloon Title goes here.");
          trayItem.setToolTip(tip);
          final Menu menu = new Menu(shell, SWT.POP_UP);
          MenuItem menuItem = new MenuItem(menu, SWT.PUSH);
          menuItem.setText("Button A");
          menuItem = new MenuItem(menu, SWT.PUSH);
          menuItem.setText("Button B");
          menuItem = new MenuItem(menu, SWT.PUSH);
          menuItem.setText("Show Tooltip");
          menuItem.addListener (SWT.Selection, new Listener () {          
              public void handleEvent (Event e) {
                  tip.setVisible(true);
              }
          });         
          trayItem.addListener (SWT.MenuDetect, new Listener () {
              public void handleEvent (Event event) {
                  menu.setVisible (true);
              }
          });         
      }
  
  }           
  </code></pre>
  
  <p>The tray are set OK but the STRING "SWT" is appearing in the side of Tray Icon as a label. </p>
  
  <p>System is Fedora Core 17 (GNOME).</p>
  
  <p>It is a platform issue or is there a way to change the text?</p>
