64bit Crash for iPad Mini

Hi All!

With the new 64bit requirement for iOS, we are trying to build our game with the follow settings.

We've tested it with a iPhone 6 and it works well, however it crashes at the start of the game when we tried it with an iPad Air.

The log when it crashes is as follows:

We are hoping that someone can help us with this issue. We are using Unity 4.6.7f1. If it helps, the game is also using the 2D Toolkit plugin.

Thanks a lot!
