Using QAssociativeIterable with a pointer as the container value corrupts the container

    QMap<QString, QObject *> mapping;
      mapping.insert("Seven", this);
      mapping.insert("Eleven", this);
      mapping.insert("Forty", this);
      qDebug() << mapping;

      QVariant variant = QVariant::fromValue(mapping);

     if (variant.canConvert<QVariantHash>()) {
         QAssociativeIterable iterable = variant.value<QAssociativeIterable>();

         // Can use iterators:
         QAssociativeIterable::const_iterator it = iterable.begin();
         const QAssociativeIterable::const_iterator end = iterable.end();
         for ( ; it != end; ++it) {
             qDebug() << it.key()
                      << it.value();
         }
     }
     qDebug() << mapping;
