Object does not match target type > App.xaml

[developer]

I downloaded the most recent source code and called the "Build_WPF40_Xamlless.bat 12/11/2013" to build the Release.NoXaml .NET 4 .DLLs.  In my App.xaml, I'm merging dictionaries:  

<ResourceDictionary.MergedDictionaries>
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/System.Windows.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.Input.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.Navigation.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.Chart.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.Data.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.GridView.xaml" />
    <ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.RibbonView.xaml" />
    <ResourceDictionary Source="Resource Dictionaries/MyDictionary.xaml" />
</ResourceDictionary.MergedDictionaries>

and I'm getting a Object does not match target type in App.xaml during design time.  If I delete the line:

<ResourceDictionary Source="/Telerik.Windows.Themes.Windows7;component/Themes/Telerik.Windows.Controls.Navigation.xaml" />

The error goes away.  Is there anything I can do to get ride of this error?

Hello Kevin,

I have tried to reproduce the described issue, but without much success. Could you please confirm that you've built the source of Q3 2013 SP release? Can you send us a small demo project?

Looking forward to your reply.
