[PyQt] PyQt5.8.2 Qml GridView TypeError: unable to convert a Python 'MyListModel' object to a C++ 'QAbstractListModel*' instance

>I can reproduce the problem. The failure happend between trigger 107 and trigger 108. At that time the C++ instances of the RuleModel objects are being deleted via calls to deleteLater() - presumably from within the depths of the QML implementation. I don't know why this is happening - it smells like a Qt bug.
