Do you mean the list in the settings? Can you try reinstalling Applist in Cydia? Someone else just had a similar issue with the app settings and a reinstall fixed it.
I have reinstalled applist but still having the same problem, as soon as I toggle one of the apps in the list it crashes the phone, the phone restarts and comes up with exit safe mode at the top of the screen. To be fair I am having quite a few instability problems so am going to reinstall iOS 6 and jailbreak again. Hopefully that should fix it.
