I'm facing the same issue with KDE 4.14.10 and it's Dolphin on FreeBSD.
I posted the following analyze to KDE and FreeBSD without any solution.
The problem is that after the initial TCP/IP exchange SYN-SYN-ACK for
the NetBIOS connect, Dolphin does nothing more and on the GUI it looks
like frozen for ever. There must be something fundamental broken in

Here is what I posted some month ago:

At work I have to access from my virtual machine running FreeBSD the
files system of the Windows 7 host (please, be patient and don't blame
me). For this I mostly use smbclient like:

$ smbclient //APITZM-LTOH/apitzm -A ~/.smbpw -I -m SMB2
Unknown parameter encountered: "display charset"
Ignoring unknown parameter "display charset"
Domain=[XXXXXXX] OS=[] Server=[]
smb: \>

which works just fine.

I tried to use the same configuration in Dolphin of KDE4, but this just
hangs. I used TCPDUMP to understand, what could be the problem.

Here is smbclient:

and this is Dolphin:

11:10:40.581878 IP > Flags [.], ack 1, win 65535, length 0

i.e. after the SYN-SYN-ACK no more traffic. 

What could I do wrong?
