Error using 'yum check-update'

I get the following when executing 'yum check-update':

[root@michaiah root]# yum check-update
Gathering header information file(s) from server(s)
Server: Fedora Core 1 - i386 - Base
Traceback (most recent call last):
  File "/usr/bin/yum", line 60, in ?
    yummain.main(sys.argv[1:])
  File "yummain.py", line 188, in main
  File "clientStuff.py", line 766, in get_package_info_from_servers
  File "clientStuff.py", line 103, in HeaderInfoNevralLoad
ValueError: unpack list of wrong size
[root@michaiah root]#

I do not know what is wrong with the python lines referenced because I
am not a programmer.  Any help will be appreciated.
