Description
-------

FTP has two modes: PASV and EPSV.
Not all server's support EPSV.

Currently, kio_ftp gives up on PASV mode if socks proxy is enabled.
That is because QHostAddress.protocol() returns -1 (unknown protocol) on KUrl("socks://localhost:3128").

So kio_ftp fails using SOCKS proxy on server's that lack EPSV support.

This patch makes sure kio_ftp will try PASV mode if socks proxy is enabled.

Testing
-------

Tested a server that lacks EPSV support with and without proxy.
Seems fine now.
Used to throw 'Internal Server error'.


Thanks,

Emil Sedgh
