This has come up several times recently...it seems as though some recent
change in e2fsck must be doing things very differently to produce this
sort of problem. I think I remember reading that the only solution is to
umount the partition in question and use ext2ed on it to delete the files.
I have similar trash in /home/lost+found on one of my systems and have not
gotten around to trying the above yet.

[root@tarkin ext2ed-0.1-8]# ls -l /home/lost+found/
