[PLUG] mount segfaults !

[Jeff Abrahamson <jeff@purple.com>]

Cool:

    krypton:~# mount /jeff
    Segmentation fault
    krypton:~# mount /jeff
    [hangs process but not machine]

I wonder why that happens.

Sending mount a SIGKILL does nothing useful, as sort of expected given
the above.

Fwiw, I had just ran mkfs.ext3 -j /dev/hdb1 (apparently successfully).

    krypton:/var/log# grep /jeff /etc/fstab
    /dev/hdb1       /jeff           ext3    errors=remount-ro       0       2
    krypton:/var/log#
