Hi Paul - that's in fact what I'm investigating....

There's a new object called 'PluginDspLoadWindow' which is getting 
displayed by Ardour but not by Mixbus for some reason.  What's failing 
is those visibility_tracker calls to 'Gtk::Widget::is_mapped()' (and 
that's why I was asking what the call does...)

Anyway, this is off-topic now for the gtk-devel list.  If I make any 
progress with it, I'll either file a bug report or maybe join you on IRC 
sometime.  Best regards,

John
