pam_mount (pam_mount-0.48-2.fc9.i386) is not able to get the password
while trying to mount an encrypted filesystem... I guess few people
uses encrypted systems over loop devices... Anyways...
That's what is shown in /var/log/messages:

Of note is that pam_mount was working about 3 weeks ago... Except it
refused to unmount the volumes when user logged off.
BTW, after Sept 19 updates rhgb stop working properly (X crashes).
