Moved the bug to 'Neon' product as this seems to be a better match
I can confirm this bug. KDE Neon User Edition
This was not really a bug in KDE but rather mismatched shared libraries... So Neon/User update of 15 Oct 2016 has fixed the problem as it provides KDE applications 16.08.2 and the new build obviously fixes the issue. Anyway, it is FIXED now
