500 error when navigating through closed Merge Requests

Some pages works fine:

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests?assignee_id=&label_name=&milestone_id=&scope=&sort=&state=closed

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests?assignee_id=&label_name=&milestone_id=&page=3&scope=all&sort=&state=closed

Other pages doesn't work:

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests?assignee_id=&label_name=&milestone_id=&page=2&scope=all&sort=&state=closed

https://gitlab.com/gitlab-org/gitlab-ce/merge_requests?assignee_id=&label_name=&milestone_id=&page=4&scope=all&sort=&state=closed

I'm guessing that we may have some orphan records.

@jacobvosmaer, can you post the backtraces of the pages that don't work?

Maybe the same as #3599 (closed)?

If it is, then it should be fixed now (8.2.0).

Status changed to closed

@jacobvosmaer @stanhu looks like it was already fixed. Thanks!
