Description of problem:
I'm not quite sure about the steps to reproduce this issue. However this is how my katello server is configured.

- Added 3 different orgs
- org1 has rhel6.2 repo synced. This is a custom repo.
- org2 has rhel6.2 synced via manifest and has pulp repo synced
- org3 has again pulp repo but with different product and repo name(here repo name is pulpy but repo url is same as in org2.
- Now the reported issue occurs only with org2 (when we switch the org1 to org2 or org3 to org2).

Version-Release number of selected component (if applicable):
[root@dhcp201-176 ~]# rpm -qa | grep katello

How reproducible:
always

Steps to Reproduce:

2. 
3.
  
Actual results:
comparison of Product with Product failed.

Expected results:
switching between different org shouldn't raise any error and sync overview on dashboard should show the proper status.
