I tried the development build. When you start it the first time it takes a few seconds until it crashes. After that it crashes instantly.

yes: 1.5.0

I can confirm, that it doesn´t work on iPhone 5 and iPad 4.
iOS 6.1 on iphone 5 and ios 6.02 on ipad 4. So it has nothing to do with 6.0 or 6.1 but (I guess) with the processor (A6) since that´s the only difference to the other devices.
