yum quit working!

[John L. Pierce]

I ran yum update yesterday and all went well the last for files updated
in my yum.log are the following:

May 10 12:12:09 Updated: gnutls.i386 1.0.20-3.1.1
May 10 12:12:11 Updated: speex.i386 1.0.5-1.1.fc3.rf
May 10 12:12:18 Updated: util-linux.i386 2.12a-24.2
May 10 12:12:19 Updated: libexif.i386 0.5.12-6.fc3

Now today when I type yum update it gives me the following and then a
quits:
Setting up Update Process
Setting up Repos
dag                       100% |=========================|    0 B 00:00

There is nothing in my logs that indicate a problem with any thing.

Below is my /etc/yum.conf file:

[main]
cachedir=/mnt/music/fc3yum
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
retries=20
obsoletes=1
gpgcheck=1

# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d

If anyone can give me a clue then I would be greatly appreciated.

John
