gstreamermm C++ vs C calls

[Russel Winder]

I have the C code:

g_object_set(G_OBJECT(play_bin->gobj()), "video-sink", video_element,
nullptr);

which does the right thing gtkmm wise in that the video widget associated with
the video_element is embedded in the right GTK container. However if instead I
use the C++:

play_bin->set_property("video-sink", video_element);

a new video window is created in addition to the one that should contain it.

I suspect I am missing something very simple.
