/var/www/piwik/core/Config/IniFileChain.php(350): Warning - array_udiff_assoc(): Argument #2 is not an array - Piwik 2.16.0 –

No reproduction scenario, according to @mattab it's not needed as it's PHP error we can catch.

Such an error is showing up for one of the environments after upgrading to 2.16, when "Save" button is clicked in General settings.
