tar woes

[Oliver Sampson]

Howdy,
I've created a tar file for a backup for my system, and I'm getting the 
following errors:

[olsam@friday olsam]$ tar -xvf olsam.tar
home/olsam/12010129.jpg
tar: Skipping to next header
tar: Archive contains obsolescent base-64 headers
tar: Error exit delayed from previous errors
[olsam@friday olsam]$

However, when I created the file, I think I used the -g option, but I 
didn't use a file name with it (the tar seemed to work just fine without 
it.)  Now, if I try to use the -g option during untarring, it requires a 
file name.  (Seems kinda of silly, but it wasn't actually incrmented 
against anything.)

So, is there a way to get the information out of this tarball?  I don't 
believe that the tarball itself is corrupt.

Thanks,
Oliver
