Why am I getting "Unable to pause activity IllegalStateException: Restarter must be created only during owner's initialization stage" in Android?

Questions:

I am using a FragmentActivity and sometimes on Crashlytics, I am able to see an exception
Fatal Exception: java.lang.RuntimeException: Unable to pause activity

Below is the onPause of my FragmentActivity

@Override
protected void onPause() {
    super.onPause();
    if (EventBus.getDefault().isRegistered(this))
        EventBus.getDefault().unregister(this);
}

Here is the stack trace of this crash.
