[Samba] major upgrade to 3.5.1, major problem

[Chris Smith]

Decided to re-compile and re-install Samba last night and with or
without the interfaces (and bind interfaces only) parameters enabled I
could not get the PDC to pass the "nmblookup -M testgroup" test and at
first it was even failing the "nmblookup -B BIGSERVER __SAMBA__".

Weird thing though, is that a Samba member server would publish
correct results to the "nmblookup -M testgroup" test - even though PDC
itself could not. Last thing I tried was setting "interfaces =
192.168.1.4 127.0.0.1" and  "nmblookup -B BIGSERVER __SAMBA__" started
working. And finally some time later (I didn't check it every five
minutes so I can't say exactly when - but it wasn't within the first
15 minutes) the PDC started to produce proper results for "nmblookup
-M testgroup".

I get this odd stuff in the nmbd log:

===============================================

It doesn't seem to like the fact that I have a secondary address on lo:
===============================================
 # ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet 127.0.0.2/8 brd 127.255.255.255 scope host secondary lo
===============================================

There is no name associated with secondary lo address as it was set
with iproute2 (ifconfig does not report the address at all).

Guide me wise Jedi master.
