Unfortunately Settings has stopped.

[dnicoll]

I am running an unmodified Nexus 7 (3G + WiFi), on KitKat 4.4.2, under ART (not Dalvik) and have just started getting "Unfortunately Settings has stopped" when I go to the settings menu. A normal reboot doesn't clear this nor does trying rebooting into recovery mode (it hangs when i try this, saying "no command"). Any ideas what is wrong and what I can do about it?

Problem was solved by rebooting into safe mode (which allowed me to access Settings), and then restoring it to Dalvik. So there is probably a small bug in ART somewhere on this (runs fine on my Nexus 5 with Apex launcher).
