Okay, after reviewing the various patches and backports, Frode's backport was correct, it was just missing the "firstEntryName = NULL;" line.
Attached is a debdiff with the "firstEntryName = NULL;" line restored. Only Focal is affected, Hirsute and Impish are working correctly.
I have a test package building in a ppa, will make a testcase now.
