Florent, your solution worked perfectly. I am using the latest Debian unstable (not Ubuntu).
I just added the line "deb-src http://http.us.debian.org/debian/ unstable main" to my '/etc/apt/sources.list' file. Then I did 'apt-get source libgnome-desktop-2-17'. Then 'cd gnome-desktop-2.30.2'. Then 'vim libgnome-desktop/gnome-bg.c' to make the one-line change that you recommend. Then 'apt-get build-dep gnome-desktop'. Then "dch -l local 'fix span'". Then 'debuild -us -uc'. Then 'dpkg -i ../*.deb'. Yeah, I did everything as root, and this is not recommended. But it worked. Now 'Span' has the right effect. Any Ubuntu user with root access should be able to do a similar thing, with sources and package names adjusted appropriately for Ubuntu.
