7.0 labeling layout elements fails with MY kendo menu.

I have an 33/67 split layout. On the left I had a submenu with treeview.

When I want to change the labele the treeview will fire an error resulting in me not beeing able to go back. Without the menu it works fine. No problem for me since I simply draged the widget out temporaraly.
