umount/ls panic

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

Hi Matt and the rest,
I just discovered a new bug. What happened is this:

ad3s2 is mount on /mnt/windows

i mounted fat32 fs (ad3s3) over /mnt/windows

cd /mnt/windows, then force umount of /mnt/windows. if you dont get a panic 
yet, try ls the directory you are in (mnt windows) and get this panic:
