yum problem with local repositories

[Mohammed El-Afifi <mohammed_elafifi@xxxxxxxxx>]

I'm using fedora 7, 64-bit edition. I'm using yum version 3.2.0. I've added a repository for the fedora 7 installation DVD by adding the following files to the file /etc/yum.repos.d/fedora.repo:

[DVD]
name=Fedora $releasever - DVD
baseurl=file:///media/Fedora%207%20x86_64%20DVD
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora file:///etc/pki/rpm-gpg/RPM-GP
G-KEY

When I try to install any development package from this repository(e.g. qt-devel), yum fetches the package and asks for confirmation to download it. After I confirm, it echos the following error messages:

Downloading Packages:

Then, I get the following error messages:
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in <module>
    yummain.main(sys.argv[1:])
  File "/usr/share/yum-cli/yummain.py", line 172, in main
    base.doTransaction()
  File "/usr/share/yum-cli/cli.py", line 302, in doTransaction
    problems = self.downloadPkgs(downloadpkgs)
  File "/usr/lib/python2.5/site-packages/yum/__init__.py", line 798, in downloadPkgs
    remote_pkgs.sort(mediasort)
  File "/usr/lib/python2.5/site-packages/yum/__init__.py", line 747, in mediasort
    a = a.getDiscNum()
  File "/usr/lib/python2.5/site-packages/yum/packages.py", line 485, in getDiscNum
    return int(fragid)
ValueError: invalid literal for int() with base 10: ''

Is this a bug in this version of yum? Or am I just missing something else?

Appreciating your feedback. Thanks for your support.
