For Future Reference:

Some quotes:

Important note: If you upgrade to MySQL 4.1.1 or higher, it is difficult to downgrade back to 4.0 or 4.1.0! That is because, for earlier versions, InnoDB is not aware of multiple tablespaces.

The Berkeley DB table handler is updated to DB 4.1 (from 3.2) which has a new log format. If you have to downgrade back to 4.0 you must use mysqldump to dump your BDB tables in text format and delete all log.XXXXXXXXXX files before you start MySQL 4.0 and reload the data.
