[SOLVED][PyQt4] , moving from pyside, subclass problem

[youmcheck]

Hi,
I' m moving some scripts from pyside 1.2 to pyqt4 and have some problems with subclass:

I' ve got a QListView that use a subclass of QAbstractListModel as model.
With pyside evrything is ok, with pyqt4 i've got this error when set the model :

TypeError: QAbstractItemView.setModel(QAbstractItemModel): argument 1 has unexpected type 'QFavorislistModel'

It' s like my subclass of QAbstractListModel 'QFavorislistModel' is not reconized as a QAbstractItemModel.

I don't understand what wrong and what are the differneces between pyside and pyqt,
If somone can highlight me,
Thanks
Arnaud
