什么会导致CurrentCulture崩溃?

What would cause setting CurrentCulture to crash?

Recently, my crash manager has emailed me a crash from a game that I'm working on.

    System.ArgumentException: Exception from HRESULT: 0x80070057 (E_INVALIDARG)
       at System.Globalization.CultureInfo.nativeSetThreadLocale(String localeName)
       at System.Threading.Thread.set_CurrentCulture(CultureInfo value)
       at Siphon_Spirit.Game1.Initialize()
       at Microsoft.Xna.Framework.Game.RunGame(Boolean useBlockingRun)
       at Siphon_Spirit.Program.Main(String[] args)

Since it was automatically emailed, I don't know where the user was located, but it seems that for their machine InvariantCulture is not set up or something.

In my initialize method I use the following code. I believe that only the two lines setting the CurrentCulture and the CurrentUICulture are causing issues.

protected override void Initialize()
    {
        this.IsMouseVisible = false;
        SetFullScreen(true);            
        SaveController.LoadOptions();
        screenManager = new Screens.ScreenManager();
        screenManager.Initialize();
        graphics.ApplyChanges();
        Window.Title = "Siphon Spirit";
        SaveController.Initialize();
        rendertarget = new RenderTarget2D(GraphicsDevice, GlobalData.ScreenWidth, GlobalData.ScreenHeight);

        debugger = new Debugger();
        Thread.CurrentThread.CurrentCulture = System.Globalization.CultureInfo.InvariantCulture;
        Thread.CurrentThread.CurrentUICulture = System.Globalization.CultureInfo.InvariantCulture;
        base.Initialize();
    }

Any ideas as to what is making it crash? This seems to be an isolated case, as more people have run it with no issues.
