@Ottomata I backported your fix and deployed it for wmf.18 yesterday before I rolled-forward the train to group1 wikis. This error hasn't shown up in the logs since.

Unclear if you were keeping this open because you planned additional work related to this task. From my perspective, it's no longer in the error log and is resolved from a production-error perspective.
