Core_Plugin_Ini::offsetSet throws exception even if $offset is valid

[pcfreak30]

in

public function offsetSet($offset, $value)
    {
        if (is_scalar($offset))
            $this->contents[$offset] = $value;

        throw new Exception('Could not set INI value: $offset must be a scalar');
    }

You need to make that an if else as setting an INI will always crash with the Exception.
