the tab headers of my ribbon control are not rendered. Initially I do not want the ribbon to be visible until the initialization process is over. So I set the visibility
of the ribbon to "Hidden" (same result with setting it to "Collapsed"). If the initialization process is over the visibility is set to "Visible". The Ribbon is then drawn without the tabs or with empty tab headers.

In Visual Studio 2010 select File=>New=>Project=>"WPF Ribbon Application"
Open "MainWindow.xaml" in the designer
Set the Visibility of the ribbon to "Hidden"

In the Click event of the button set the visibility of the ribbon to "Visible" as follows
private void button5_Click(object sender, RoutedEventArgs e)
Ribbon.Visibility = System.Windows.Visibility.Visible;
Start the application. The ribbon is invisible as expected.
Click on the Button and the ribbon is visible but the header of the ribbon tab is not
