什么是这个set_Visible异常的起源在关闭winforms应用程序

我已经包装了应用程序。在try/catch

[STAThread]
private static void Main(string[] args)
{
   try {
       MyClient client = new MyClient();
       client.Run(args);
    }
    catch (Exception ex) { log.Error("Failed to start client",ex); }
}

Where MyClient is just:

class MyClient : WindowsFormsApplicationBase

在每次关机时我都会得到这个异常

System.ObjectDisposedException: Cannot access a disposed object.
Object name: 'MainView'.
   at System.Windows.Forms.Control.CreateHandle()
   at System.Windows.Forms.Form.CreateHandle()
   at System.Windows.Forms.Control.get_Handle()
   at System.Windows.Forms.Control.SetVisibleCore(Boolean value)
   at System.Windows.Forms.Form.SetVisibleCore(Boolean value)
   at System.Windows.Forms.Control.set_Visible(Boolean value)
   at System.Windows.Forms.Application.ThreadContext.RunMessageLoopInner(Int32 reason, ApplicationContext context)
   at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context)
   at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.OnRun()

   at Microsoft.VisualBasic.ApplicationServices.WindowsFormsApplicationBase.Run(String[] commandLine)
  at MyProgram.Main(String[] args) in C:'svn'trunk'MyProgram'client'MyProgram'Program.cs:line 54

如果我在catch块中的调试器中设置了一个断点，那么除了client.Run(..)之外，我的调用堆栈都是空的。

就我所能理解的堆栈跟踪问题是在某个地方，一些代码正在做MainView.Visible = ....，但我可以在我的代码中找到任何类似的东西。

如何找出异常的来源?

MainView是这样在MyClient中创建的:

protected override void OnCreateMainForm()
{
   string[] args = Environment.GetCommandLineArgs();
   try {
        MainView mainView = new MainView(args);
        this.MainForm = mainView;
        Application.EnableVisualStyles();
        Application.Run(mainView);
   }catch(Exception ex){ log.Warn("Exception in OnCreateMainForm",ex); }
}

像这样结束:

public void OnKilled()
{
   log.Debug("OnKilled. Exiting");
   Application.Exit();
}

MainView定义如下:

public partial class MainView : Form
{
    private void InitializeComponent()
    {
        this.FormClosing += new System.Windows.Forms.FormClosingEventHandler(this.MainView_FormClosing);
    }
    private void MainView_FormClosing(object sender, FormClosingEventArgs e)
    {
        log.DebugFormat("'MainView_FormClosing': {0}",e.CloseReason);
        if (e.CloseReason == CloseReason.WindowsShutDown || e.CloseReason == CloseReason.ApplicationExitCall)
        {
            e.Cancel = false;
            Application.Exit();
        }
}
