I submitted the first changes last night. Would have hacked out the little errors sooner but I had huge problems with upgrading movable type. Everything from files not transferred properly (or at all) by the FTP client to problems to the usual "ObjectDriver, DBI::mysql" issues. To anyone facing similar issues I'll give the following heads up.
- backup your previous install including all files and database
- reinstall all the files again, configure mt-config.cgi to point at your databaseand hope it all works
