Description of problem:
Libreoffice crashes while trying to copy and paste anything.
The defect happens on afew computers that where former Fedora23s which where updated to Fedora24 via "dnf system-upgrade".

This happens both on 32bit and 64bit installs.

Version of Libreoffice:
=================
libreoffice-5.1.4.2-4.fc24


Additional info:
===========
On some of these machines I created a new "clean" user and as a result Writer stops crashing, while Calc still keeps on crashig after every "select" attempt.
