if vpnc has an issue on it's own, then NM is certainly impacted by the same...
it's in essence a GUI frontend calling vpnc in the background.

Now of course, vpnc did not get any package changes for about a year - so
finding what broke will be fun.

You mentioned after updating to 20151014 you saw the problem: do you happen to
know from which snapshot up updated from (previous would have been 20151012,
but there is a good chance of course you don't dup daily)

> grep openSUSE-release /var/log/zypp/history | tail

should give the required info (maybe you need a longer tail in case you updated
too often since then)

With this info, we might at least have a chance to narrow down what all might
have changed
