[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thisiseric:
Hmm, it has been working with every release thus far. I just tried doing the same thing with the YouTube app and the same behavior was exhibited. I'll wipe and start from scratch.

Edit- Nope, still crashing. Can other people try this? Pause a YouTube app video and wait for it to go to sleep. Mine constantly forces a reboot.

This is the logcat of a fresh install with YouTube causing a reboot.
