Clicking on RichTextBox Hyperlink with RadTreeView throws Exception

[Anton Trinkunas]

Hi

In very simple scenario RadTreeView throws exception. User should just click on hyperlink. Here is xaml code:

<Grid x:Name="LayoutRoot" Background="White">
        <StackPanel>
            <telerik:RadTreeView >
            </telerik:RadTreeView>
            <RichTextBox IsReadOnly="True">
                <Paragraph>
                    <Hyperlink NavigateUri="http://www.google.com">
                        Silverlight</Hyperlink>
                </Paragraph>
            </RichTextBox>
        </StackPanel>
    </Grid>

If to remove RadTreeView from xaml everything works fine.
Here is exception:

System.InvalidOperationException: Reference is not a valid visual DependencyObject.

   at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)

Reproducible on RadControls 2012_1_326.
