lxterminal on lubuntu on a raspberrypi2 segfaults due to this bug (or at least that's what it looks like to me)

I have the same issue on a normal (non-desktop) Ubuntu 18.04 running XMonad with Gnome and using the gnome-shell.

[Matteo Bronkhorst (matbronk)]

I have experienced this since a few days as well. For me, this also seems to cause not being able to logout or switch users. I hope a fix will be found soon.

[Artiom Neganov (aneganov)]

I have the same issue on Kubuntu 18.04

[josergc (josergc)]

I got this in lubuntu 18.04 running dolphin-emu

my uname -a values:

any update on this issue?

[Neal Lithwick (nlithwick)]

I have the exact same issue. I cannot log out or shutdown my system by either using GUI log out or through the terminal using "gnome-session-quit" (for log out)

I'm seeing it after rebooting my 18.04 machine today.

Any update on this case? I'm seeing this on Ubuntu 18.04 LTS except while running KDE

Today, on my Xubuntu system

Distributor ID: Ubuntu
Description: Ubuntu 20.04.4 LTS
Release: 20.04
Codename: focal
5.13.0-37-generic x86_64

I saw the error message from the headline of this bug report in /var/log/apport.log:

This occurred on a special installation on my "yellow" USB3 stick (instead of the built-in SSD) that I have made for maintenance purposes.

Do I need to worry about the error message?

Is it possible that this is why the boot process from the stick takes so long?

Trying to find the reason why the boot process takes 2:45 minutes with the screen being black for 1:30 minutes was the reason for me to look for error messages in `/var/log` and on this occasion I came across the error message.
