Well, some unglamorous stuff: I've verified that what gets set in 
Glib::ObjectBase::_set_current_wrapper() is the same as what gets 
returned by Glib::ObjectBase::_get_current_wrapper().

The dominance thing seems like it's worth looking into, I have no idea 
what it means, will be looking it up this evening.

One other possibility that occurs to me that perhaps this is a problem 
with calling virtual functions in a constructor, didn't you say that 
moving the call to show() in your example makes things work?  See
