Comment 14 for bug 355081

I hade a quick look at the code in wallpaper tray. When it selects a random wallpaper, i does not only load the wallpapers in the path selected, it always also consider all the wallpapers in the gnome wallpaper selector. (The list you can see when you right click the desktop, and select "Change desktop backgrounds") All of those are stored in the .gnome2/backgrounds.xml file, but that file will be regenerated when you open the "Change desktop backgrounds". Some one might contact the developer of Wallpaper tray and request af feature to disable the loading of the gnome backgrounds.
