Nexus 7 Unity 5.1.2 crash

We are having a crash issue with our app on one of our Android devices. Even starting with just a fresh Unity 5.1.2p3 (or 5.1.2p1) project and an empty scene, the android build crashes on the device. On most of our devices it is fine, but on our Nexus 7 running Android 4.3, it crashes immediately (before splash screen) with “Unfortunately has stopped.” We have tried all sorts of build and graphics settings combinations of device filters (ARMv7, x86, fat), API Level (15, 18) Graphics APIs (OGLES2, OGLES3, Automatic), Api Compatibility Level (.NET 2.0, .NET 2.0 Subset), removing shaders, and lowering quality settings.

To add to the weirdness, we have 2 Nexus 7’s, and the crash happens on only one of them. It crashes on the one with Kernal version 3.4.0-g1f57c39, and not on the one with Kernal version 3.1.10-g1e8b3d8

Upgrading to the beta Unity build 5.2.0b6 seems to fix the crash, but we are reluctant to release with a beta build of Unity. Because this crash is currently blocking our release, we were wondering of a) the release date of 5.2.0b6, and b) if there is a patch happening for this issue on 5.1.

edit below is the logcat created at the crash
