special character kde crash

LibreOffice 5.2 makes my KDE desktop completely crash as soon as I try to inser a special character. It sometimes did back on LO 4.4, but now it’s become common practice. Rather annoying to be thrown back to the login screen, just because I want to say ë, à, ü, ß or £. Any solutions?

Specs: LibreOffice 5.2.0, installed from Fresh PPA, on LinuxMint 17.3 (Ubuntu 14.04 LTS), with KDE 4.14, Qt 4.8.6, and kernel 3.19.0-32

EDIT: I found my own work-around. See: LibreOffice minor misfortunes – Grazige Weiden
