I've just upgraded to Ubuntu 15.04 and first noticed that this problem has been resolved, but there are still some complications it seems.
When I ran Nautilus as root (using the command "gksu nautilus") I suddenly saw that the Unity Launcher background switched to the default background again. What's worse, when I tried getting rid of it by entering terminal command "nautilus -q", I saw that my desktop background changed to default one. ** Attachment added: "Screenshot" https://bugs.launchpad.net/unity/+bug/1241757/+attachment/4384042/+files/Screenshot%20from%202015-04-25%2017%3A26%3A27.png -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[TEST CASE] (1) Configure the desktop to use a non-default wallpaper. (2) Log in to a Unity session and observe the area behind the Launcher. [REGRESSION POTENTIAL] The solution to this problem was to eliminate the animation of the BFB icon on initial startup. Potentially this could cause the animation to not run at other times, although even if this did occur, it is unlikely to be noticed. [OTHER INFO] The fix for Ubuntu 14.04 LTS was cherry picked from the Ubuntu "Vivid Vervet" dev release where it has been in production use for some time without apparent regression.
