Description of problem:

Note this is very similar to https://bugzilla.redhat.com/show_bug.cgi?id=1361793 but has a different root cause.  

Here is the relevant traceback:

 | NoMethodError: undefined method `name' for nil:NilClass

Given the code:

        <td><%= link_to h(report.policy.name), policy_dashboard_policy_path(report.policy) %></td>

It seems that there is a report without a defined policy
