Description of problem:

I mirror the fedora repository locally, but not the debuginfo packages.  So, I
have repos configured like:

[updates-testing]
name=Fedora Core $releasever - $basearch - Updates Testing
failovermethod=priority
baseurl=file:///data/sw1/fedora/core/updates/testing/$releasever/$basearch/
enabled=1

[updates-testing-debuginfo]
name=Fedora Core $releasever - $basearch - Updates Testing - Debug
baseurl=http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/$releasever/$basearch/debug/
enabled=0
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora

No, with util-linux-debuginfo-2.13-0.20.1 installed, and -0.20.4 available from
updates-testing-debuginfo, I run into the following problem:

Why is it trying to use the url from [updates-testing] instead of
[updates-testing-debuginfo] ?
