When a seemingly secure password throw off the requirements for a secure password

I tried to update my password at Logitech and generated a password consisting of 2048 characters, mixed uppercase, lowercase, digits and special characters. When submitting my request with the new password, the form show a message (in this case in Danish) that it is easy to guess short keyboard-patterns (what ever that means).

Do you have other interesting/funny/silly examples of password-requirements?
