The "Layered" option for auto keyframing will create a new NLA strip if playback reaches the end of the frame range and jumps back again. The idea is that instead of overwriting the keyframes you've already made, it will make a new animation layer. However, this does not work with the "Insert Available Only" option (which can either be set in the User Prefs, or in the active keyingset), as that option needs some existing FCurves to tell what it can insert keyframes into. The "fix" here is to simply not show the offending button in situations where it cannot be used!
