[Mono-dev] Gecko-Sharp & WebControl.NewWindow Event Handler.

When one registers an event handler for a Gecko-Sharp
WebControl.NewWindow event, one receives the following exception when a
viewed page attempts to open a popup window.

System.ArgumentNullException: Value cannot be null.
Parameter name: type
     at System.Activator.CreateInstance(Type type, Boolean nonPublic)
     at System.Activator.CreateInstance(Type type)
arg0, IntPtr arg1, UInt32 arg2, Int32 key)
     at Gtk.Application.gtk_main()
     at Gtk.Application.Run()
     at WinFormTest.GeckoSharpWin.Show(String url) in c:\\documents and
settings\\btimby\\my documents\\work\\winformtest\\geckosharp.cs:line 90

This happens on Both Windows and Linux, running Mono

I have attached sample code. To test, create an app to instantiate the
attached class, provide the Show method a url to a page that opens a
javascript popup, and see what happens.

How would you go about troubleshooting this? I cannot find the source
code to libgtk-win32-2.0-0.dll. Furthermore, how can I get my hands on
the symbols (for Visual Studio .NET) for the Gecko-Sharp and Gtk-Sharp

Thank you.
