    No revision is set for this page (lastrevid) - maybe T115081

    Looks like T115081, judging by DB content and the stacktrace:

    This task is about the production fatal error.

    If it can't be triggered by logged-out or plain URL, and if it is considered unimportant by product, and if we don't want to work around it and look at the root cause instead, then please mark it as stalled with T115081 as subtask.

    Until then, re-opening for now.
