Could not update ~/.ICEauthority after ecryptfs-rewrap-passphrase wrapped-passphrase SOLVED

Hello,

I wanted to change my login password on my personnal account on my Gnu Linux Debian Wheezy, so I do this :

$ su root -
# cd /home/.ecryptfs/seb/.ecryptfs
# ecryptfs-rewrap-passphrase wrapped-passphrase

I gave the old password ( my login password ), then the new, then I changed my login passwd :

# passwd seb

And after a reboot, I fell on this nice message : 

Could not update ~/.ICEauthority

I could not enter on my own account :-(((
