Description of problem:

Running System Update fails with the exception trace in the Actual Results section below.  Attempts to install just a few of the 162 updates results in a same error, "Caching enabled but no local cache", minus the exception trace.  I have tried yum clean all, as well as deleting deleting the cache (/var/cache/yum) and recreating the cache (yum makecache).  The same error results.

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

An F11 KVM (x86_64) running on an F11 host (x86_64).

How reproducible:

Very (on my system).  I have 3 F11 KVM VMs.  Two were cloned from another.  All reconfigured with different static IPs and are able to resolve domain names on the Internet.  All (as expected) have the same exact error and exception trace.

Steps to Reproduce:
1. Run "Software Update" from the System->Administration menu
  
Actual results:
