All I had to work off from is the following:

http://gotpenguin.com/gnome/tutorial/ch-ctreewidget.html

I've since found the docs here

http://developer.gnome.org/doc/API/2.0/gtk/gtkctree.html#gtk-ctree-move

and find that you are right.  For anybody else that might reading this
archive for this "problem", using gtk_ctree_move to temporarily move the
branch and then using gtk_ctree_remove should solve the problem.

Thank you,
