displaying luks-passphrase unencrypted.

[Machtin]

Binary package hint: usplash

When i boot, I'm asked for my luks-passphrase, to decrypt my /home-partition.
The password then is displayed as ******..., however, when i enter the pass and go to tty7 via ctrl+alt+f7, i can read the passphrase i just entered!
i consider this a security bug.. I'm currently running 2.6.30-9, but i've noticed this at least since 2.6.28
