    Description

      The attached qml script provides a testcase for the mentioned crash. When using a list, property of a ListModel item, as a submodel, the clear() method on such submodel causes a SEGFAULT. Though removing items one by one does work fine.

      Testcase:

      • Click on window
      • Click on created item
      • Crash
        Program received signal SIGSEGV, Segmentation fault.
        0x00007ffff62bfc56 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/qt4/libQtCore.so.4
        (gdb) bt
        #0 0x00007ffff62bfc56 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) ()
        from /usr/lib64/qt4/libQtCore.so.4
        #1 0x00007ffff7b102ef in QListModelInterface::itemsRemoved(int, int) () from /usr/lib64/qt4/libQtDeclarative.so.4
        #2 0x00007ffff796ec1c in QDeclarativeListModel::clear() () from /usr/lib64/qt4/libQtDeclarative.so.4
        #3 0x00007ffff7b0ef90 in QDeclarativeListModel::qt_metacall(QMetaObject::Call, int, void**) ()
        from /usr/lib64/qt4/libQtDeclarative.so.4

      Expected results:
      The list should be cleared with no problems.
