SUMMARY
ksshaskpass --version (or --help) crashes when executed outside KDE session.
See the coredump below
STEPS TO REPRODUCE
1. login to linux via SSH
2. type ksshaskpass --version
OBSERVED RESULT
ksshaskpass --version
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it
was found.
This application failed to start because no Qt platform plugin could be
initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen,
vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.
zsh: IOT instruction (core dumped) ksshaskpass --version
EXPECTED RESULT
Getting version info or help despite GUI is running in different session, it
should not be needed.
