Test program for gtk bug

["E. ALLAUD" <e allaud wanadoo fr>]

	Hi all,
here follows a small test program to demonstrate gtk bug : just run it 
and click on the button, you'll see tha the tree is scrolled down to 
the row 9 which is expanded, but the selected node is one step below. 
This is not what is intended by the code which should scroll to the 
first child of the "9" node. If you do the same after the "9" node has 
been expanded you'll see that gtk scrolles correclty to the first child 
of "9".
Is it OK for you that I post that to bugzilla?
Bye
Manu
