why don't you keep this with other wallpaper info, that way you'd avoid two
storage change events for a single wallpaper change (first only for name, and
then the rest of the info)? And source third app name _is_ part of wallpaper
info.

(sorry that I didn't notice wallpaperInfoKey in previous pass)
