What are the file permissions? 
What version of the kernel are you using?
What filesystem are you using?
Have you run an fsck lately?
Have you done any changes to it using chattr? (unlikely problem, but 
possible)

ls should show it if you're able to edit it, even when it's owned by 
another user and
group with permissions 000

There may be a bug with the filesystem code.
If you're using reiserfs, and you've used an older hash and have changed 
to a newer
hash this could be causing it.  If you're using reiserfs and you've used 
a newer hash
to create the filesystem and now you're using an older hash, this is 
definitly the
problem (from my experience).  If you're using kernel v2.4, there may be 
problems with
the filesystem (here comes the flames...), every possible bug cannot be 
worked out
with an initial 'stable' release, any new changes to the ext2 filesystem 
or even the
disk controller driver can cause problems with your filesystem.  If you 
are running
reiserfs, unmount the filesystem and do a reiserfsck on it.  Check the 
journal integrity
field.  Remount the filesystem read-only, reiserfsck it again.  Check 
the journal integrity
field.  If either checks shows a problem with the journal integrity, 
you'll need to backup
all your data and recreate the filesystem.  If you run into any errors 
backing up your
data, then you can revert to your old kernel (you still have it right?) 
and try again.
If not, it's gonna be a long process trying to get all your old info, 
unless you've got
backups (you do backup regularly right?).
