Шаблон класса 2

Здравствуйте. Тут проблемка:
template <class T> class Konteiner{
private:
QVector <T> vect;
public:
void locate(T &x){
cout << vect.indexOf(x) << endl;
}
};

Вызываю так:
Kombi_figure cir_tr(cir_z,tr);
Konteiner<Kombi_figure> kon;
kon.locate(cir_tr);

Ругается так:
/usr/local/Trolltech/Qt-4.4.1/include/QtCore/qvector.h: In member function ‘int QVector<T>::indexOf(const T&, int) const [with T = Kombi_figure]’:

Подскажите, что делают не так? Заранее благодарю.
