Bug in Unity4.3.4 crash on Application.Quit() with simple test project?

I made a very very simple project to confirm this.
When I call Application.Quit(); the android activities time out.
My device is a “Acer A500 Tablet” - 1GB Ram, Dual-Core Tegra2, Android 4.0.1.

Test Code:

Logcat - EDIT: I was getting timeout errors that would just keep the device black that I forgot to put in the log. You have to wait a few seconds before it prints them after the whole system lags out.

Same thing for my DroidX phone.
Android 2.3.4.

Logcat:

I’m having the same Issue, but when I press back button while loading something like with “LoadLevel” or “Resoures.Load”. When the game it’s loading (freezed while loading) and I press back button, the game crashes and exits.

Anyone knows something?

I’ve posted this also at http://forum.unity3d.com/threads/179785-Android-back-button-crash-in-first-scene?p=1540927&viewfull=1#post1540927

I pretty sure I did a test on Unity 4.2.2 and this issue did not exist. I think this is a 4.3+ but bug.
NOTE I messed up in my post and didn’t post the FULL LOG. I was getting time out errors after hitting the back button, not “com.unity3d.player.UnityPlayerNativeActivity paused=false” as thats normal behavior.

You have turned on option Developer options → Do not keep activities. Just turn it off and everything will be fine.

How do you get to this file menu option?

It’s in the Settings App of Samsung Devices under More > Developer options > Apps (scroll down) > Do not keep activities
