Images + labels in buttons

[John Stebbins <stebbins jetheaddev com>]

In previous versions of gnome/gtk, both images and labels appeared in 
buttons.  Starting with gnome 2.28, if there is a label, the image will 
only appear if the gconf property 
desktop/gnome/interface/buttons_have_icons is True.  In my application, 
the image on some buttons is an important clue to the function of the 
button.  Is there any way to force the image to be displayed regardless 
of the setting of buttons_have_icons?
