Looks like a bug in file context.
chcon -t xferlog_t /var/log/vsftpd.log
should fix it.
I will update policy

I've got that one sorted, deleted the logfile and restarted vsftpd.
Now got other problems:
Need anonymous ftp, configured ftpd correct (I think).
Created a user "ftpuser" for anoymous ftp in /var
ls -Z looks like this:
drwxrwsrwx ftpuser ftpuser system_u:object_r:ftpd_anon_t ftp
In ftp I have
drwxrwsrwx ftpuser ftpuser system_u:object_r:ftpd_anon_t pub
And get 553 errors,
TYPE I
200 Switching to Binary mode.
PORT 192,168,0,2,6,45
200 PORT command successful. Consider using PASV.
STOR 465_v6.pdf
553 Could not create file.
Transfer request completed with status: Failed, 1 SubItem(s) failed
