check out the type mismatch in init's first parameter:

no call to: init(ConstraintTypesBrowser*&, void*&, void (SigC::Object::*&)())
candidates: init(SigC::Object*,            void*,  void (SigC::Object::*)())

Is ConstraintTypesBrowser is SigC::Object subclass?  It would if it derives from
a gtk widget.  If it is not a subclass, simply make it one ...

class ConstraintTypesBrowser : public SigC::Object
{
  ....
};
