SSL/TLS connection is not working over SOCKS5

SSL/TLS connection is not working over SOCKS5
Tested FileZilla versions: 2.2.3 and 2.2.4b

Connection is estabilished successfully, but retrieval
of directory listing fails.

I try to connect to an SSL/TLS-supported ftp-server
with explicit encryption, going through a SOCKS5 proxy.
It doesn't work with using a proxy and works without
the proxy (that means direct connection between
FileZilla and the ftp-server).

Attached three session logs:

• sample log for a connection using SOCKS5 proxy (and

FileZilla 2.2.4b)

• sample log for direct connection between FileZilla

and ftp-server

• sample log for a session using CuteFTP Pro v3.3 as

client and SOCKS5 proxy (just for demonstration
purposes ... it shows that a connection _is_possible_
between the client machine and the ftp-server using the
SOCKS5 proxy and explicit SSL/TLS encryption)

sample sessions logs for both with and without proxy connections
