Duplicate of https://bugs.kde.org/show_bug.cgi?id=355711, which is already fixed in a later version than what you have available in Ubuntu 16.04.

Your options are:
1. Live with this crash
2. Upgrade to a later version of Ubuntu (or a different distro)
3. Apply the Kubuntu backports PPA to gain access to faster-updating KDE packages
