[arch-general] KDE Dolphin Network Services : Fail to open ftp server

[set]

Hello,

On my home network is a UPnP/FTP/Samba server which I can access normally 
through these protocols from many devices.

On ArchLinux, FTP access through a URL in Dolphin's address bar works simply. 
Browsing fails through the pathway : Network/Network Services/FTP 
servers/ServerName.

Error message (crude translation from French) :
	can't connect to host servername.local : timeout reached when trying to 
connect to remote host.

The error is displayed immediately.

The same attempt succeeds on Fedora 16 in the same home network.

Any help to solve this out is welcome.

Thanks in advance.
