Demonstration header file and configuration file.

When template member function has no parameters doxygen generates duplicate entries in the documentation.  For example this:

/*! \brief AClass is documented. */
class AClass {
public:
    template<typename C> class AChildClass;
    //! \name GroupA
    //!@{
    template<typename C> AChildClass<C> amemberfunc();
    //!@}
};

/*! \brief AChildClass is documented. */
template<typename C> class AClass::AChildClass { };

/*! \brief Member is documented. */
template<typename C>
AClass::AChildClass< C > AClass::amemberfunc()
{ return something(); }

results in amemberfunc showing in both under GroupA and under public.  The above provided as an example with matching config file in the attached.
