loop encryption problem

gentoo problem:

icebird ~ # mount -t reiserfs /dev/hdc1 /secure/ -o loop,encryption=XXX
Password:

Error: Password must be at least 20 characters.

Just recompile:
ACCEPT_KEYWORDS="~x86" emerge "=util-linux-2.12i-r1"

I think this should only be a temporary solution. rebuild your encrypted partition with a correct password!
