that is because google added a new permission request from apps which they don't usually request.
but alas, there is fix, if you're working with one of the latest versions of JB (quarx or epsylon3 it doesn't matter) you can fix it by simply by following the next steps:
1. make sure your'e phone is rooted and has superuser or any other permission manager app (superuser zip flashable can be downloaded here)
2. enter the app drawer and enter the "terminal emulator"
3. gain root permissions by typing :
wait for the notification about permission allow/deny, and allow it.
4. now you give permission to the program you want by writing the following line:
pm grant [programs name] android.permission.READ_LOGS
(the upper case /lower case is important)
I.E for catlog you should type:
su pm grant com.nolanlawson.logcat android.permission.READ_LOGS
now your logging app should work fine, enjoy!
