Arch Linux

Description: When I try to save every kind of LibreOffice document the application crashes when I press Save As or Export. This doesn't happens if I open Libreoffice's menu then Tools>Options>General and uncheck "Use LibreOffice Dialog Windows".
I also tried to force using gtk vcl in /etc/profile.d/libreoffice-fresh.sh and /etc/profile.d/libreoffice-fresh.csh but nothing happened.
