    Description

      When QtCommercial Charts 1.2.1 is built against Qt 5.1.0 Beta1, all qml demos that have more than one view (e.g. qmlaxes demo) crash when changing the view the second time. This release worked fine against Qt 5.0.2. It seems that the fix for QTBUG-28187 (https://codereview.qt-project.org/#change,41612) causes this regression, as the crash goes away if it is reverted.

      The crash can also be reproduced without charts by adding a QGraphicsWidget element to qml in a multi-view application, see the attached example.
