Fixed for 5.20

After updating my Gentoo box to 5.20, the Log Out and Shut Down buttons in plasma stopped working.  They just cause plasma shell to crash.  After reverting the change mentioned in comment #2, the buttons work again.  A backtrace of the crash follows:

This was actually caused by bug #457285.
