Description of problem:
I created a repo and created filter to black list the packages. But when I promoted the product to next env. pulp.log raised a traceback. No error in katello production logs and filters are working in katello.

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

How reproducible:

Steps to Reproduce:
1. create a provider ==> custom product ==> repo
2. create filter 
3. sync repo 
4. create changeset, update changset

Exact steps:

katello> repo create --org sghai_org --name pulp_x86_64 --product pulp --url http://repos.fedorapeople.org/repos/pulp/pulp/testing/fedora-15/x86_64/
Successfully created repository [ pulp_x86_64 ]
katello> filter create --name filter2 --packages grinder,gofer --org sghai_org
Successfully created filter [ filter2 ]
katello> product add_filter --name pulp --filter filter2 --org sghai_org
Added filter [ filter2 ] to product [ pulp ]
katello> repo synchronize --org sghai_org --product pulp --name pulp_x86_64
Repo [ pulp_x86_64 ] synced                                           
katello> changeset create --org sghai_org --name pulp_promo1 --env test 
Successfully created changeset [ pulp_promo1 ] for environment [ test ]
katello> changeset update  --org sghai_org --name pulp_promo1 --env test --add_product pulp
Successfully updated changeset [ pulp_promo1 ]
katello> changeset promote --org sghai_org --name pulp_promo1 --env test
Changeset [ pulp_promo1 ] promoted         
  
Actual results:
no issue in katello, filters are working fine but a traceback in pulp.log
