Triaging as Meta/Low priority for the time being as I've not been able to reproduce this on a wiki besides test.wikipedia.org. It is still likely to be a real problem, but at least the particular circumstances required for it (e.g. a combination of two extensions registering certain preferences) is not being triggered elsewhere.

Belay that. I can reproduce it on ca.wikipedia.org now. Submitting the form at https://ca.wikipedia.org/wiki/Especial:Llista_de_seguiment consistently produces:

This error is not seen on earlier branches and not yet seen on group2 wikis (which run wmf.20). As such, marking as regression.
