This solution works for me (so far) :
- delete registry value "ubuntu_sso" in key "HKEY_CURRENT_USER\Software\Ubuntu One\Keyring" (I suppose it's the Ubuntu SSO security token).
- reboot computer
- sign-in for a new Ubuntu One token.
- it's working again !!!
Just to be sure, I rebooted again, and it still syncs.
Me... yet again.

I hope it will for others too. :-)
