This seems most likely to be a 'bug' in CentralNotice -- we are leveraging wgOut's parser instance instead of creating an instance for ourselves -- but apparently that has a dependency on being fully initialized which is not when in a maintenance script.

Is this blocking vanadium->zinc migration, is there a bug for that and is current priority appropriate for this report?

Testing on testwiki indicates it works. I'm just letting it finish up if you want to take its output.

That seems to have fixed bug 52148 too.
