Using QT_QPA_PLATFORMTHEME=kde outside a Plasma session is completely unsupported. In any case, post a backtrace with debug symbols to see if there's anything obvious, but this is definitely not a packaging problem.

Short and Full backtraces attached.

Nothing obvious from the backtrace. Use qt5ct to configure Qt outside a desktop environment, KDE platform theme is only for Plasma.
