Our gnome desktop defaults to loading 'default.png' for a background. We've named all our DNA files default.jpg, thus gnome won't load it. I've temporarily linked default.png to default.jpg, however a real fix would be either making these files pngs or making gnome fall back to default.jpg in the absense of default.png
Lets make 'em pngs for FC6, and fix the capplet for FC7
Not sure how that would come about: /etc/gconf/default_gnome_background.schemas has <default>/usr/share/backgrounds/images/default.png</default>
err, or rather: we just need to change the schema
I've updated the schema in libgnome-2.16.0-2, so we can drop the .png symlink again.
The symlink is long gone. Everything works fine.
