Recently I was having SD Card problem, but after some experiment i think i have found a temporary solution. If the Live Wallpaper is in internal memory and not running from SD Card, this error is not occurring in my mobile. As for example, Nexus Revamped resides in internal memory. U can check it by unmounting SD Card and then going to home screen, if the live wallpaper stays then it is running from internal memory. Guys, u can check your in your mobile and provide the results here.
