[Glade-users] Bad behaviour of GtkVBox

[mferrero at reer.it (Manuel Ferrero)]

I have a GtkVBox vbox1 with 3 items in a GtkWindow.
In vbox1 I have two GtkVBoxes and a GtkHButtonBox, packed from end in 
position 0, 1 and 2.
If I select vbox1 and then in the General tab I change number of items 
to 4 I can't change it back to 3, even if the newly added position is empty.
I was able to solve it removing the child in the .glade file and reload 
it in Glade.
Is this a bug I have to file?

I enclose my .glade file.

Glade 3.8.1
Windows XP
