I am also now just having this problem. @ first i was wondering what i did and then all of a sudden it started working again. I think the app that is messing with my app manager is the 'Desktop Activity' that saves your desktop. Thats the only thing i can think off at the moment that has messed with it. Ever since i put that app in it has started to give app manager problems. I just dont understand as to why it sometimes works and sometimes it doesnt.

I think it only works when i reboot the phone.=/ any ideas anyone? I am going to probably uninstall that app but thats weird because i thought that app was already in extras now.
