Google Cardboard signal 11 (SIGSEGV) error

Hello, I use Google Cardboard SDK (0.6) in my Android application.
But when I resume the Cardboard app, sometimes it crash.

This is a Android Home Applcation.
My app include
<category android:name="android.intent.category.DEFAULT"/>
<category android:name="android.intent.category.HOME"/>
in AndroidManifest.xml

So, when I click the home button, it crash.

Here is my crash log.

A couple of quick questions: What version of Unity are you using? What Cardboard viewer?

 

Hi, I use Google Cardboard for Unity3D 0.6v, and I use Unity 5.1.2f.
I updated Unity 5.3.1, but the issue is still occurs..
I think this intent flag is cause when call Home app.
Intent.FLAG_ACTIVITY_NEW_TASK
