Bug 2378694

Description of problem:
Per https://bugzilla.redhat.com/show_bug.cgi?id=2378661#c0, I invoked this application from an SSH client on postmarketOS. The cause of the problem appears to be that $DISPLAY is unset. It solely appears to affect Qt-based applications (not merely KDE Frameworks-based ones). However, it doesn't affect all, for VLC copes fine. (Likewise, the GTK3-based Chromium and Inkscape cope.)

Version-Release number of selected component:
krename-1:5.0.2-10.fc42
