When making a QSharedPointer use deleteLater, you should really pass in a custom deleter like so:

   QSharedPointer<MyClass> instance(new Myclass(param), &QObject::deleteLater)

i.e. at object creation time. It's risky to grab the raw pointer from a shared pointer and ask it to delete at some point.
