Loading gdl layout from file

Hi, I'm trying to understand this gdl. Mostly from the anjuta, scaffold
and screem sourcecodes.

I have a problem with getting the loading from file working.

If I do:

dock = gdl.Dock()
layout = gdl.DockLayout(dock)
item = gdl.DockItem("board", "Board", None, gdl.DOCK_ITEM_BEH_NO_GRIP)
item.add(gtk.Label("..."))
dock.add_item(item, gdl.DOCK_LEFT)

everything works fine,
but if I add:

layout.save_layout("__default__")
layout.save_to_file("/home/thomas/layout.xml")
layout.load_from_file("/home/thomas/layout.xml")
layout.load_layout("__default__")

suddently item.parrent == None and nothing appears in my window.

I've added tons of shows and show_alls, but the problem seams to be,
that the item is no longer attached to the dock. If I do
dock.get_children() I get an empty list.

Do anybody know how to overcome this?
