Description of problem:

Performing:

yum --releasever=20 --enablerepo=updates-testing --enablerepo=updates distro-sync

on a updated Fedora 19 (x64) dependency resolution will fail.

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

Fedora 19 (x64) updated at October, 8th.
Linux localhost.localdomain 3.11.3-201.fc19.x86_64 #1 SMP Thu Oct 3 00:47:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:

Did yum clean all
Did rpm --rebuilddb
Did updatedb
Did yum repolist
Did yum --releasever=20 --enablerepo=updates-testing --enablerepo=updates distro-sync

In my system, by doing the yum command above.

Actual results:

--> Finished Dependency Resolution
Error: Package: dnf-0.4.2-1.gitc1716d7.fc20.noarch (updates-testing)
           Requires: python-librepo = 1.2.0
           Available: python-librepo-1.0.0-1.fc20.x86_64 (fedora)
               python-librepo = 1.0.0-1.fc20

               python-librepo = 1.2.1-1.fc20
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Expected results:

Update transaction will end without errors.
