Description of problem:

A client reported failures while attempting to import the EPEL5 repo into their satellite. I had a look and replicated the issue using pulp directly to simplify testing. The issue appears to be that the updateinfo errata metadata in the repo doesn't have "description" elements defined for all of the erratum. The pulp-rpm importer doesn't much like that and fails.

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


How reproducible:
Always

Steps to Reproduce:
1. pulp-admin rpm repo create --repo-id=test_epel5_pulp --display-name="RHEL5 EPEL" --feed=https://dl.fedoraproject.org/pub/epel/5/x86_64 --relative-url=epel5 --serve-http=true --serve-https=true
2. pulp-admin rpm repo sync run --repo-id=test_epel5_pulp
3. Fail.

Actual results:
[root@satellite updateinfotest]# pulp-admin rpm repo create --repo-id=test_epel5_pulp --display-name="RHEL5 EPEL" --feed=https://dl.fedoraproject.org/pub/epel/5/x86_64 --relative-url=epel5 --serve-http=true --serve-https=true
Successfully created repository [test_epel5_pulp]

[root@satellite updateinfotest]# pulp-admin rpm repo sync run --repo-id=test_epel5_pulp +----------------------------------------------------------------------+
               Synchronizing Repository [test_epel5_pulp]

Additional info:
Having a look at the updateinfo for EPEL5:

As a sanity check, EPEL6 doesn't have any such discrepancy:
