So a word akin to German "Maler", then? Is there a medieval dialect in which a form of such a word might have been written as "mallier"?

I don't think so. In all Germanic languages, the "a" was long, so we would expect only one L. If it has anything to do with painting, I think a Romance form is more likely. Too bad the rather clear word "aller" exists in about any relevant language.
