Ticket created, but still no ideas what this mean...
Can you test on clean Miranda NG installation? Create ICQ account in NG, but dont enter UIN/pass. Instead go to protocol options, click "Create new account" (this button also allows you to login by phone number). Enter phone number (linked to your account), request SMS and enter code. Press OK to close registration window, but please do not press OK or Apply in Options window. Just press Cancel.
Try to login.
