Fedora 25 NetBios/wins issues

I am trying to set up local hostname resolution on my Fedora machine. I have installed

-winbind samba-winbind-clients pam_krb5

and then went through the procedure shown on: https://www.server-world.info/en/note?os=Fedora_25&p=samba&f=3 I have added wins to my

/etc/nsswitch.conf

as follows:

:      files mdns4_minimal [NOTFOUND=return] dns myhostname wins

I then try to use wins to find my raspberry-pi which I can find on my Ubuntu install. If I add wins before myhostname I get:

$ ping my-pi
Segmentation fault

When it is as shown above I get:

$ ping my-pi
ping: my-pi: System error

Any pointers on how to diagnose/solve this issue would be much appreciated.
