Comment 10 for bug 321742

I think this patch introduces some problems of its own. Should I report a new bug?

If I do the following Do crashes with the error below.
1. Start do 1106 with meatcity compositor enabled
2. Open a window (eg Firefox)
3. Toggle the compositor off
5. Summon Do (it turns up in Classic Mode)
6. Toggle Compositor back on
7. Click on an item in Docky that has a window associated with it.

Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
GLib.MissingIntPtrCtorException: GLib.Object subclass Do.Interface.ClassicWindow must provide a protected or public IntPtr ctor to support wrapping of native object handles.

Hope that helps,
