All GTK+ signals are executed through a glibmm SignalProxy object, and the connect() method that glibmm/gtkmm present you with is a connect method of the proxy, not of a sigc::signal object. The connect method of the SignalProxy takes a second bool 'after' argument, which by default is true. Pass a value of false to the 'after' argument of the connect method if you don't want that. Annoyingly, this is the obverse of GTK+ signals, which by default execute the connected callback before the built in handler.
