Is this a "new" problem, or just newly discovered? If it is a "new"
problem, what changed?

It's almost impossible to even guess based on only the above.

This is completely normal.

This is normal too. The lists that don't have config.db and
config.db.last files were created under Mailman 2.1.x. Those that do
have them were migrated from 2.0.x. In fact it is a good idea to
remove the config.db and config.db.last files from the lists that have
them. Otherwise, if the config.pck and config.pck.last files ever get
corrupted, Mailman could fall back to the config.db or config.db.last
and then you'd wind up with a years-old configuration and membership
