Android 5 portrait app crashes when going to Recents and rotating

The activities of my app have all the attribute to make them portrait:

android:screenOrientation="portrait"

The minSdkVersion of the app is 21. With Android 5.0 phones the app crashes if the device is using the autorotate setting and the app goes to background (Recents/Overview screen) and then the device is rotated.

When this happens, this is the stacktrace I get from the error:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.ActionMenuPresenter.updateMenuView(boolean)' on a null object reference

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:1194)

The problem seems to be in the onCreateOptionsMenu. This is the reduced version of my main activity:

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    override fun onCreateOptionsMenu(menu: Menu): Boolean {
        super.onCreateOptionsMenu(menu)

        menuInflater.inflate(R.menu.menu_mainpages, menu)
        val menuItem = menu.getItem(0)

        val profilePictureView = LayoutInflater.from(this)
                                                        .inflate(R.layout.profile_image_layout,
                                                                 coordinator_main,
                                                                 false)
        menuItem?.actionView = profilePictureView

        return true
    }
}

The reason for this crash was using ActionMenuView as the root for my layout profile_image_layout and not setting it up correctly. Since I didn't really needed it, I switched to a different view class as root and the crashes are not happening anymore.
