MvxPreferenceFragmentCompat inconsistent crashing

[woody1987]

Steps to reproduce

1. Create a MvxPreferenceFragmentCompat, without using a custom layout.

Expected behavior

Should display preferences

Actual behavior

Display preferences the first couple of times, then will seemingly at random through an error

				return true;
		}

		return base.OnOptionsItemSelected(item);
	}
}

Configuration

Version: 4.3.0
Happens on Android 4+

Not sure what is going on here. We don't inflate any layouts ourselves or manipulate any views. This is just a simple wrapper around PreferenceFragmentCompat which exposes a couple of events.
