Bug#980119: libgnutls30: "An unexpected TLS packet was received" when connecting to FTPS (FTP/TLS) servers

[cacatoes at tuxfamily.org]

No success on my side, it times out, or doesn't seem to send/process the
USER/PASS if I input them, maybe I was late this time.
The server has IP blacklisting so it doesn't help...

~~~
$ gnutls-cli --starttls-proto=ftp myftphost -V
Processed 126 CA certificate(s).
Resolving 'myftphost:ftp'...
Connecting to 'ip.ip.ip.ip:21'...
Negotiating FTP STARTTLS
starttls: sending: FEAT

starttls: waiting for: "211 "
starttls: received: 220 Some Welcome Message

starttls: received: 521 Not logged in - Secure authentication required

USER myuser
PASS error receiving '211 ': Timeout
~~~

With the same host but with Filezilla it was able to receive the
certificate before trying to Login.

With some other host (the one used by OP) I receive the certificate and
go into simple client mode, so it could have worked.
