Bug 63351 [Navigator] Import/ExportResourcesAction not removed as listeners of selection service
Open and closing the navigator view, these actions are leaked. It would appear that the dispose for these actions is not getting called?

!selection.isEmpty()
				&& ResourceSelectionUtil.allResourcesAreOfType(selection, IResource.FILE);
		
	
		MenuManager newMenu =
			new MenuManager(ResourceNavigatorMessages.getString("ResourceNavigator.new")); 
		menu.add(newMenu);
		new NewWizardMenu(newMenu, navigator.getSite().getWorkbenchWindow(), false);
		
		gotoGroup.fillContextMenu(menu);
		openGroup.fillContextMenu(menu);
		menu.add(new Separator());
		
		refactorGroup.fillContextMenu(menu);
		menu.add(new Separator());
		
		menu.add(importAction);
		menu.add(exportAction);
		importAction.selectionChanged(selection);
		exportAction.selectionChanged(selection);
		menu.add(new Separator());
				
		if (onlyFilesSelected) {
			addBookmarkAction.selectionChanged(selection);
