'secondary' is the cursor class for the particular backend; in your case, Firebird. Apparently the Firebird cursor requires more than the standard arguments. Can you look at the kinterbasdb and/or fdb code to see what arguments are required for the cursor class's __init__() method?

When that code was written, we were probably using 2.2 or 2.3. It's been working fine all these years, so we never updated it. But even if we removed the use of 'apply', there would still be only 2 arguments being supplied.
