BreadCrumbItem ItemTemplate issue..


Hi, I'm trying to use this fantastic object, and I'm expecting a strange issue when I want to use a "keyed" HierarchicalDataTemplate for BreadCrumbItems.
My Xaml is something like this:
<BreadcrumbLib:BreadcrumbItem ItemsSource="{Binding Source={StaticResource MyList}}" ItemTemplate="{StaticResource MyListTemplate}">
<Image Source="Journal.png"/>
where MyListTemplate is defined as follows:
<HierarchicalDataTemplate x:Key="MyListTemplate" DataType="{x:Type src:League}" ItemsSource="{Binding Path=Divisions}" >
  <TextBlock Text="{Binding Path=Name}"/>
If I remove ItemTemplate from BreadcrumbItem everything works, but if I use a "keyed" template it doesn't work.
Is there something I missed or is this a kind of bug?
Thanks Enrico
