FullPath returns rubbish

[Trude]

I'm trying to synchronize a treeview and a breadcrumb and I use the following code

BreadCrumb1.Path = RadTreeView1.ContainerFromItemRecursive(RadTreeView1.SelectedItem).FullPath

The FullPath returns: "Project1.hierarchy_tab\Project1.hierarchy_tab\Project1.hierarchy_tab"
In this case I'm three levels down in the treeview.

Both controls are databound to the same observable collection (I'm using internal Q2 build 0823)
