At restoring unencrypted data Déja Dup wants password

view story

http://askubuntu.com – When I try to restore data that I did not encrypt, I need to enter an encryption password. Recently I upgraded from Ubuntu 11.10 to 12.10. In the older version I made a backup without encryption of the /home folder. Under my own user name I never had to enter an encryption password. Under another user name, Déja Dup did ask for a password when that other user wanted to make a backup. After the upgrade "something went wrong". Now I want to restore my files from /home. All my files are gone. How do I restore my files? Thanks & regards (HowTos)
