I've seen this behaviour, but only when the directory being listed is empty. When not using SSL, an empty directory listing will result in the data connection being opened, and then closed without any information being sent. In SSL mode, then connection is closed before the SSL is negotiated and any client will report a handshake error. The RFC is ambiguous as to what should happen in this situation, and although some UNIX FTP servers send a 550 response instead, I believe this specifically breaks the RFC. Does this tie up with what you are seeing?
