Using 7-12-stable (installed from source) after having upgraded from 5.3 (!) with non-negligible effort, yet successfully, we are getting 500 error when trying to access a projects merge-requests e.g.

https://<base_url>//merge_requests?assignee_id=&author_id=&label_name=&milestone_id=&scope=all&sort=created_desc&state=merged

Error details from production.log:

Same error occurs for state=closed and state=all

We have followed the installation instructions and migration (upgrade) instructions e.g. here: https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/patch_versions.md

We also upgraded 7-12-stable to 7-13-stable (from source) and performed all migration however still getting this error.

Help?!
