I was able to reproduce that error easy enough even though I don't care about resizing the navbar. The error occurs after you change the navbar dpi and then select reboot, if you don't select reboot, no error. Logcat attached.
What you are looking for should be near the end, not a dev but looks like it has something to do with lack of reboot permissions.
