Status in “ecryptfs-utils” source package in Ubuntu: Confirmed

Bug description:
Binary package hint: ecryptfs-utils

~$ lsb_release -rd
Description:	Ubuntu 8.10
Release:	8.10

$ apt-cache policy ecryptfs-utils

  Installed: 53-1ubuntu11

Trying to set up a ~/Private with a mount passphrase containing any parentheses ( "(",")" ) will initially be accepted but the script will fail on trying to add the passphrase to the keyring:

# Add the passphrase to current keyring
# On subsequent logins, this should be handled by "pam_ecryptfs.so unwrap"
response=`printf "$MOUNTPASS" | ecryptfs-add-passphrase -`
if [ $? -ne 0 ]; then
        error "Could not add passphrase to the current keyring"
fi

This has worked previously.
