[Solved] Bug in RadScaleTransition

Hello
I think this is a bug, when using RadScaleTransition and a ScrollVierwer on a page, when navigating to a new page and then when I return and tap anywhere on the page I get the following error:

at MS.Internal.XcpImports.CheckHResult(UInt32 hr)
   at MS.Internal.XcpImports.UIElement_HitTestPoint(UIElement element, Point ptHit)
   at System.Windows.Media.VisualTreeHelper.FindElementsInHostCoordinates(Point intersectingPoint, UIElement subtree)
   at System.Windows.UIElement.HitTest(Point point)
   at System.Windows.Controls.ScrollViewer.OnManipulationStarted(ManipulationStartedEventArgs e)
   at System.Windows.Controls.Control.OnManipulationStarted(Control ctrl, EventArgs e)
   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)

This does not happen on other transition types, is it a bug in the Scrollviewer, RadScaleTransition or am I doing something wrong.  Below  sample xaml that reproduces the error.
/regards Ove
