Solve the following python programming problem given the following code:
def __call__(self, func) : 
    'Returns a wrapped version of the called function.

        :param function func:    Function that should be wrapped.

        :return:    Returns a wrapped version of the called function.
        :rtype:     function
        ' 
    def wrapped_func(* args, **kwargs) : 
        'This function gets executed, if the wrapped function gets called.

            It automatically created a performance profile for the corresponding function call.
            ' 
        profiler = profile.Profile () 
        result = profiler.runcall (func, * args, ** kwargs) 
        filename = ('%s' % self._filelocation) 
        profiler.dump_stats (filename) 
        return result 
self._func = func 
    setattr (wrapped_func, '__name__', self._func.__name__) 
    setattr (func, '__repr__', self._func.__repr__) 
    setattr (wrapped_func, '__str__', self._func.__str__) 
    setattr (wrapped_func, '__doc__', self._func.__doc__) 
    return wrapped_func 

    
    

    Fix the buggy line: setattr (func, '__repr__', self._func.__repr__)

#Here is Python code to fix the buggy line: setattr (func, '__repr__', self.
