Apparently GtkSharp expects each object has only one ToggleRef at any time. Assigning element.Handle into Raw has a consequence that second ToggleRef attempts to get created but fails on g_object_unref () that breaks a GObject assertion: toggle_refs_notify: assertion failed: (tstack.n_toggle_refs == 1) This is because toggle references should be removed with g_object_remove_toggle_ref(), not a simple unref(). In order to avoid duplicate toggle references, introduce ElementFactory.MakeRaw(), which creates a GstElement without its accompanying C# object. The returned raw pointer can be assigned into another GLib.Object without trouble. Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/1885>
