Cannot log out through "session management" power button in xfce panel indicator plugin...

STEPS
======

•Select the Session Management button within the XFCE panel's xfce4-indicator-plugin.

•Select "Log Out..."

•A dialog is shown with button options:

    "Cancel"

    "Log Out..."

•Select "Log Out..."

Expected Result
================

The dialog box should disappear, applications should terminate, the user should be logged out, and the session should be closed.

Actual Result
==============

The dialog disappears, and nothing else happens. The user session is not closed. The user is not logged out. Applications continue to run.

Note
=====
Logging out by selecting the Log Out button within the popup dialog after selecting the power button in the whisker menu works fine.

It may not matter, but I should note that I installed Ubuntu 17.04 just 4 days ago, and immediately installed the xubuntu-desktop package. I'm currently using the xubuntu-desktop option as my DE.

I believe it is the same as https://bugzilla.xfce.org/show_bug.cgi?id=11758

Though in that description, the reporter claims the user can achieve session logout through repeating the action twice. I've tried logging out multiple times, and nothing happens.

Same as here:

Is this related to:
