Android freeze on load (black screen with title)

Even with an empty project (just the default settings and objects), I'm getting a lock up when I launch the game on Android 2.3.7. This lock up continues until I am given the option for Force close (if I try to press some of the hardware buttons). The game runs with no problems at all on Android 4.3. I am using Unity 4.6.1f1.

I have tried turning on/off the 32/24 bit buffers. Any more ideas would be very much appreciated. Thanks!

The abridged output from adb logcat is:

         I/ActivityManager(  166): Start proc com.sifnt.androidtest for activity  com.sifnt.androidtest/com.unity3d.player.UnityPlayerNativeActivity: pid=2668 uid=10073 gids={3003, 1015}
         I/AndroidRuntime( 2660): NOTE: attach of thread 'Binder Thread #3' failed W/ActivityManager(  166): Launch timeout has expired, giving up wake lock!

         E/ActivityManager(  166): Reason: keyDispatchingTimedOut

And the traces (I don't know what any of this means but it might be useful to someone):
