Description of problem:
After noticing that my server is out of sync, I've tried the manual rhn_check. The error doesn't give me any clue as to the cause of the error. I will try installing the updates manually to see if the problem can be reproduced with other packages.

Version-Release number of selected component (if applicable):
up2date-4.4.50-4

How reproducible:
Always

Steps to Reproduce:
1. select some updates in rhn.redhat.com to be installed on the target system.
2. run rhn_check or rhn_check -v.


Actual Results:  I received an error:

Expected Results:  The updates downloaded and installed.

Additional info:

I even tried setting up2date to just-download the updates and am still getting the same error after the package list. I am using a proxy server without authentication.
