I think the "problem" is that on your system the default is to not show
images in buttons (this is GNOME's default since 2.28). I guess the
image shows up normally if you turn
on /desktop/gnome/interface/buttons_have_icons in gconf.

I am not sure what the correct way is to force an image to be shown,
even if that option is off. But I am not sure either whether that is a
good idea anyway.
