[pygtk] Drag and drop: retaining selection?

I'm trying to set up DnD in my program to retain the selection after
dragging, but I can't seem to get it work. We have some rather crazy
code to handle the drag and drop itself (which I can paste but I don't
think it's relevant) because the TreeModel simply mirrors a backend
list which we have to update. In Glade, I've connected 'drag-end' to
my after_drag_drop callback, and set it to call *after*. Here's the
def after_drag_drop(self, treeview, drag_context):
model = treeview.get_model()
sel = treeview.get_selection()
# self._selected is created in the DnD code, and is simply a list of
for path in self._selected:
The treeview's selection mode is set to gtk.SELECTION_MULTIPLE.
It seems like it works (just eyeballing it), because the selection
'sticks' for a moment, but then the selected rows are unselected. Any
idea what would be causing this or what other code I could paste to
help figure this out?
Thanks a lot,
