Prodding at this briefly with "git blame" leads to the below commit. 
Perhaps mmeeks can comment :)

     Fixup legacy sleepycat db database usage for packages

     Previously empty legacy registered_packages.db databases were created
     unconditionally, at some efficiency and startup cost, despite these
     being deprectated since before version 3.2.
     We now handle version mismatches by warning on the console and ignoring
     these files.
