Comment 6 for bug 1115886

I have also got the same issue with Gnome-shell ubunut 13.04 beta 2. I also only have to set show-desktop-icons to true.

But i use gnome-tweak-tools and i alwasy disable "Have fiel manager handle the desktop" becouse it slows down nautilus the first time you open it. This option sets show-desktop-icons to false. But i also used gnome-tweak-tools in ubuntu 12.04 in the same way. But this did not effect my background.
