TreeStore reordering

[Charles Schmidt <cschmidt2 emich edu>]

I'm a bit confused about how reordering cells in GtkTreeView 
using GtkTreeStore is supposed to work in Gtk+ 2.2.1.  I 
have a TreeView with a TreeStore with the following cells 
(pardon the poor ascii art):

-Folder 1
-Folder 2
    -Folder 3
          -Folder 4

I am able to drag and reorder Folder 4 to a child of Folder 
2, or child of the non-existant root (ie, on the level with 
1 & 2), but I cannot drag it to be a child of Folder 1.  Or, 
if I drag it out of Folder 3, I cannot drag it back in?  Is 
this how reordering is supposed to work with the TreeStore, 
or is it a bug in my application (test case provided) 
somewhere, or what?
