How reproducible:
always

Steps to Reproduce:
1. Import valid manifest. Enable repo set and repo "Red Hat Enterprise Linux 6 Server RPMs x86_64 6Server "
2. Create content definition, add that repo into it, publish, and promote to "test" environment.
3. Create activation key with promoted content view and add RHEL repo pool into key.
4. Subscribe client via activation key. It will show error: "undefined method `provider' for nil:NilClass".

Actual results:
error is shown

Expected results:
it should register successfully

Additional info:
when activation key does not contain resource pool, it works fine.
