I made those amendments to the perl files on my system. Initially it looked
like it completed a full backup sucessfully and I was breathing
a sigh of relief. But I had also set in the config for that host to ignore zero
byte responses from tar ($Conf{BackupZeroFilesIsFatal} = 1;) and that
combined with these amendments meant the backup completed successfully - but it
had actually not backed up any data at all!
My backups are a lot of very small files and a normal full backup can take 2-3
days. So I was suspicious when it had finished within
a couple of hours - which would be ok for an incremental but far too soon for a
full backup.
I'm somewhat reticent to rollback to an earlier samba 4.1.6 as I don't want to
risk a dependency mess that ends up costing me
more time and effort in resolving later. I had a brief look at rolling back
with apt and aptitude and it looked somewhat risky.
I also thought maybe I could just get the required smbclient and related
dependency binaries and put them in place manually by
renaminmg the existing ones and simlinking to the older binaries. But getting a
generic binary was harder than I thought!
Samba only provides source. Switching to use rsync on the windows side instead
of smb might be the easiest short term fix.
I read somewhere that only requires 4 files and one of them running a service,
I'll have to look into that.
But the sooner a patch is released that fixes this all the main distros the
better (in my case Debian Jessie).
One thing I'm learning from this is containerizing my backuppc using dockapps
in a modular fashion and possibly virtualisting
that so I could have snapshots of the system state would be very useful in this
sort of situation.
Ordinarily when something goes wrong with a system you can rely on backups but
when the problem is the backup system,
the stakes are higher!

After making changes to the Smb.pm and Browse.pm files, I have 2 Windows
servers backing up and 4 in the process of backing up.
The only change I made was that indicated in this post:
https://bugzilla.redhat.com/attachment.cgi?id=1111264&action=diff
Browse.pm changed this:
From:
if ( !defined($In{num}) && defined(@Backups) && @Backups > 0 ) {
to
if ( !defined($In{num}) && @Backups > 0 ) {
Smb.pm changed this:
From
} elsif ( /^\s*tar: dumped \d+ files/ ) {
to
} elsif ( /^\s*tar: dumped \d+ files/
|| /Total bytes received: \d+/i
) {
and inserted this line
|| /^tar:\d+/
between:
} elsif ( /smb: \\>/
and
|| /^\s*added interface/i
so it reads:
} elsif ( /smb: \\>/
|| /^tar:\d+/
|| /^\s*added interface/i
I hope this speeds up someones resolution.
