Description of problem:
Occurred when I invoked `qdbus-qt6 org.kde.Shutdown /Shutdown org.kde.Shutdown.logout` multiple times, consequtively, when Konsole was preventing logout. Similarly to https://bugzilla.redhat.com/show_bug.cgi?id=2390813#c0, except that I was able to report https://bugs.kde.org/show_bug.cgi?id=508726#c0.
