I guess you should try:

Glib::RefPtr<Pango::Context> pContext = win.get_pango_context();

or

Glib::RefPtr<Pango::Layout> pLayout = win.create_pango_layout("Pango Test 
Application");

The output sounds as if some fields of the context were not set.
But I'm learning this stuff myself at the moment so please let me
hear whether this helps...
