Straight after logging to Xfce4, logout not works: DBus must be in idle state

I use Devuan Excalibur with Xfce4, Xorg, Slim on Intel i9-12900. When I login to slim Xfce4 starts and I am seeing some autorun scripts did not start, try to logout. But log out is not executing, so I am clicking "Application button" on Xfce4-panel and get such error window with such message:

"DBus: Logout error. Dbus must be in idle state to logout."

But after 10-15 seconds it finally log out.
