GTK dialog ESC key problem

[Colossus <colossus 3000 it>]

Hi,

I have a gtk-dialog built with glade with the two buttons Cancel and 
Ok. When I push the ESC key on the keyboard the code behaves as I 
clicked Ok with the mouse on the dialog and this is not correct.

How can I avoid this behaviour ?
