Gtk.RecentManager：列出项目的方法

Question

我想列出所有“最近使用过的”商品。 我使用这段代码：

public static void Main(string[] args)
{
    Application.Init ();
    RecentManager rm = RecentManager.Default;
    GLib.List items = rm.Items;
    Console.WriteLine(items.Count+" items.");
    foreach(object item in items)
    {
        Console.WriteLine(item.ToString());
    }           
    Console.WriteLine("Done.");
    Console.ReadKey();
}

如果Items-list为空，则按预期工作。但是，如果RecentManager确实包含Items，我将得到：

3 items.

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

我处理Gtk＃/ GLib时是否有错误？ 我已经重建了我的单一环境。

Gtk-sharp邮件列表helped out：
这是known bug，但存在变通方法。以下代码有效：

public static void Main(string[] args)
{
    Application.Init ();
    RecentManager rm = RecentManager.Default;
    GLib.List items = new GLib.List(rm.Items.Handle, typeof(RecentInfo), true, true);
    Console.WriteLine(items.Count+" items.");
    foreach(RecentInfo item in items)
    {
        Console.WriteLine(item.DisplayName);
    }           
    Console.WriteLine("Done.");
    Console.ReadKey();
}
