Comment 14 for bug 549268

As a papercut , I'm a skeptical of this change , we already *do* set the wallpaper by default . Nothing is going to be improved for a new install.
Why the need to force it along with the theme? Even if it does not force a change , This change would mean we will end up with a prompt for *ever* , if the user wishes to change the wallpaper. Do we want to always keep prompting the user to use the wallpaper. If the prompt is to occur only once this might be a better.[ But even then why?] How does it improve user experience?
Further the prompt reduces the theme viewing area.

David Siegel, I'm inclined to mark it invalid. what do you think?
