--- Begin Message ---Package: libpam-mount Version: 0.28-1 Severity: normal Hi, when logging in as root and then su-ing to a user account everything works fine. But at logout the su-command seems to have dropped root privileges, so umount fails.

I suppose this is most often the case. Ah, and i noticed that when the mounting of the crypto loop device fails (such as when root is guessing the wrong password when su-ing to the user account) a loop device is leaked. Anyway this setup is rather useless so i only would make another detailed bug report if you want me to.
