[CentOS] FTPS setup problem

I threw that configuration you posted on a working vsftpd (working without 
SSL) on CentOS 5 and can only confirm that it doesn't work. One obvious 
problem is port 990 as ftps wants to connect via port 990. In Filezilla 
you can choose to use FTPES which seems to connect to port 21 and force an 
SSL auth. This actually works as you get the certificate displayed to 
accept it and you can login. However, the directory listing fails. I tried 
changing to active, disallowing certain protocols etc. It all fails at the 
same stage.
The link posted (http://bugs.proftpd.org/show_bug.cgi?id=3094) seems to 
apply exactly to this situation. So, you simply will not be able to work 
with a newer Filezilla client against a vsftpd server without this patch.
