It rebooted again tonight, about 24 hours after the factory reset.
Also, intermittently now the power button will not suspend the phone, though I can hold it and reboot, I don't know any other way to put it to sleep.
Looking at the log some more, the only thing that gives any hint is that there was Location Services activity before the crash. Googling around about my problem showed there was a bug in Location Services early in 4.2 but the claim was that it was fixed. I guess tomorrow night I'll try turning off Location Services as well.
The update may have screwed up somewhere in the middle, you could try to re-ruu your phone or unlock the bootloader and flash a custom rom, also the thing about the power button not putting the phone to sleep or doing anything than reboot on long press happened to me on each and every custom rom and I never did any OTA, got my phone, unlocked bootloader and flash away from sense, my hboot is still the one that it came with, but for me that thing happens really randomly, like once every 1 or 2 weeks, and when that happens for me the volume buttons stop working also till reboot, I was thinking I was the only one facing it so I kinda decided not to talk about that as I saw no one say anything about it, but I am also one of those for who the phone turns off exactly when my phone goes to 6% battery whatever I do, on whatever rom I am and even in the recovery, so I was thinking that maybe vodafone modified something on it, that's an other reason I didn't say anything about the buttons becoming unresponsive...
So what I would recommend is to re-ruu your phone or go to a custom rom (or if none solves anything the phone may have some kind of hard brick).
