[BetterBatteryStats] XlAfbk:
Yes, you can :) The same issue existed in the beta builds, but I assumed it was a Superuser problem then. Reported it to koush but it's obviously not fixed yet.

Here's a screenshot http://img824.imageshack.us/img824/1176/screenshot2013030413455.png As you see it allows it most of the time but sometimes denies.

got a logcat of when it was happening ("db denied"). including some lines before and after, i've save the full log in case it's needed:
