Question PHP 7 and Kunena: Call to a member function get() on string

Joomla 3.5.1
PHP 7.0.6
Kunena 4.0.10 | 2016-02-18 [ Villavicencio ]

A non logged-in user clicks the menu-item "Kunena Forum » Startseite". This results in an error message

Call to a member function get() on string

If a user who is already logged in clicks the menu-item "Kunena Forum » Startseite" it works all right.

Thank you and kind regards
Christof
