CentOS - Jul 2008 - Centos 5.2 upgrade - urlopen error unknown url type: media

My first notebook upgrade:

I repaired my old HP nc4010 (bought a new hinge on ebay) and realized 
this was the perfect way to test out the upgrade to 5.2 before doing it 
on my production notebook.

First I updated to 'current' 5.1 (by current I mean I have not synced my
5.1 local repo since building my 5.2 repo).  I had not used my nc4010 
for a while and the kernel was at 2.6.18-53.1.13 (update took it to 
1.21).  Rebooted and system still working.

I then pointed my CentOS-Base.repo to my 5.2 repo.  I did a yum clean 
all then a yum update yum* rpm and below is what happened:

======================================================
I rebooted my local repo server.  No change.

I downloaded a new copy of yum-metadata-parser-1.1.2-2.el5.i386.rpm from 
mirror.centos.org/centos/5.2/os/i386/CentOS/.  No change. (dated Jun 14, 
mine was dated Jun 24, the day I built my repo. but file sizes are 
identical).

What am I missing here?

Searching the local folder of this list reveals two older postings from 
you about this (one from December, one a few days ago). It seems to 
indicate that your repo is not completely in sync. Either a new sync or 
clean all got you going last time ;-)

The other times a

yum clean all

did the job.  Problems with old metadata, it would seem.

This time I did the clean first and still got the error.

I ran a rsync and did not get any updates to base.

I should also mention that right now, I have a fresh install foranother 
system running off this repo.

The problem is deeper than this.  I know that my local repo is being hit 
for the 5.2 files.  See that in the log.  I just completed doing a yum 
update on the system I just did an install.

I get the message with different rpms based on what I want to update.  
yum update yum gets the parser as noted.  yum update rpm gets the 
message for the rpm rpm.  yum upgrade gets it on chkconfig.

So there is something that got on this system from one of the 3rd party 
repos that is causing the problem.  Perhaps some MIME lib that I picked 
up from rpmforge, jpackage, or kbsingh....

http access log on my repo server says otherwise.

Yes, I have lots of installs, updates, and upgrades running here.  Lots 
to bring up to snuff.  And a hand full of problems.

This system was my workhorse from the start of 5.0 until back in 
January.  So it has rpms from all over I suspect there is something 
there that is causing this.

Oh, I have run yum -d 5 -e 1 --noplugins

and this does not help or show where things are wrong.
