After selecting Shutdown from the Kmenu/leave page, nothing happens - the menu closes, but the shutdown promt does not appear. Ksmserver CPU usage jumps (100% on a single core). Reselecting shutdown does not help. Shutdown goes smoothly (no error is visible) by using systemctl shutdown or shutdown -h now. After killing ksmserver process, the screen goes black then the login screen appears. Reproducible: Sometimes Steps to Reproduce: 1. Open Kmenu 2. Select shutdown 3. ??? Actual Results: Nothing happens, except ksmserver start using 100% cpu on a single core. Expected Results: The system should present the shutdown dialog, then shut down. I have no shutdown scripts registered. The issue was present on previous versions too, but was rarer.
I've just experienced the bug again, and I've got to make some changes: After ksmserver CPU usage jumped to 100%, trying to bring up systemmonitor or Ksysguard was unsuccessful (Ctrl+esc did not work, krunner hanged). After killing ksmserver by sending TERM signal, window decorations disappeared, but both the system monitor and ksysguard opened up. I could not recover the session, had to restart it by restarting X.

After restarting X and signing in, shutdown worked flawlessly.
The bug seems fixed in 5.5.0
