[Solved] Setting DataContext of hosting Control for the RadDiagram causes UI Links to crash

[John]

Hello,

In a UserControl, setting up the following causes the RadDiagram to crash when the Connectors are clicked when running

<Grid x:Name="LayoutRoot" Background="White">
  <telerik:RadDiagram >
    <telerik:RadDiagramShape />
  </telerik:RadDiagram>
</Grid>

In the code behind

namespace SilverlightApplication1.Classes
{
    public partial class Test : UserControl
    {
        public Test()
        {
            InitializeComponent();
            this.LayoutRoot.DataContext = this;
            //Comment out the line above to resolve the issue
        }
    }
}

Please could you let me know if there is something incorrect, with the changing of the datacontext, 
or if there is something that I should be doing instead?

I am using version 2012.1.507.1050 of the assemblies.
When the application is running, click any of the connector nodes. 
The application crashes with :
    Exception has been thrown by the target of an invocation.
        {System.ArgumentException: Value does not fall within the expected range.
