lxsession-logout doesn't appear sometimes

When I try to run lxsession-logout (fro menu, or from terminal emulator), it sometimes (very often) doesn't apper on the screen, but exists on running processes.

I have the latest version of the package:
apt-cache policy lxsession-logout
lxsession-logout:
  Installed: 0.5.2-0ubuntu3
  Candidate: 0.5.2-0ubuntu3
  Version table:
 *** 0.5.2-0ubuntu3 500
        500 http://ru.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages
        100 /var/lib/dpkg/status

As temporary solution I run lxsession-logout in terminal emulator for immediatly terminate program with Ctrl+C, when it didn't appear, and try again. After several repeats it appears on the screen.

It was on Ubuntu 14.04, and now it also on 16.04.
I use manual package installation, maybe it's depends on some specific package?

There is a log of my installation (on Russian, but you can find there installed packages):
16.04: https://github.com/Avol-V/my-light-ubuntu/tree/5f1fed7e09b0d6f645203ae11c9de5cdaa4501a7

I have the same problem with this installation on two different computers.
In both situations I install pulseaudio instead of alsa and didn't install compton.

On one of my computers I have nvidia videocard with proprietary driver, but on other (notebook) I have intel hd4000 intergated video with free driver. I have problem in both cases (I did not use compositing on any of this configurations).

I create a small video-recording of this issue: https://youtu.be/jXB6SzKzGNs
In this video I successfully run lxsession-logout after first kill, bt sometimes it much harder.

There was a simular bug, but now it marks as fixed: https://bugs.launchpad.net/ubuntu/+source/lxsession/+bug/1534798
