Remove the maxlenght from the Kopete::Password API
It make no sens to limit the maximum size of a password you ask to the user. The user should know the lenght of his password.

That code was introduced beause ICQ has a limit of 8 for the password length, but the official client do strip the password, so the user may think it has a longner password. The correct way to do it in Kopete is the same: strip the password.
