Invalid Socket 8 and type 'Read', disabling... on logon

Hi,
When I try to logon KDE 5, I have a black screen and a cursor, I still can launch anything I want using ALT+F2, and I still can have Yakuake with F12, I don't know if it's because of an update,
I tried to logon from SDDM and manually from a TTY terminal, with no difference,
I tried to start manually Plasmashell from a terminal (both "plasmashell" ans "kstart5 plasmashell", but no difference...), and it complained with 2 lines :
Code: [Select]
QSocketNotifier: Invalid Socket 8 and type 'Read', disabling...
QSocketNotifier: Invalid socket 9 and type 'Read', disabling...
Here is further information when launched from a debugger :
Code: [Select]

I don't really understand what happened, I found nothing that could help on Internet, I tried to create a dummy user account to check if the issue is caused by a bad file in .config, .local, .cache, etc., but I have the same problem...
I really don't know what to do now, so I'd be glad to get some help.
Here are my specs :
- Motherboard Asus Maximus Extreme
- CPU : Intel Core 2 Quad Q9650
- 12GB RAM
- GPU : Nvidia Geforce GTX 550 Ti
- OS: Artix Linux

Check to see if dbus is running by user before you start and see if that makes a difference.
Read some here: https://dbus.freedesktop.org/doc/dbus-launch.1.html

% export $(dbus-launch)
% xinit
anti-X  - artix - obarun - Void - systemD Free Space

I can no longer participate in a public forum side by side with neo-nazis and NSA trolls in a moderated sterile environment that is good for business.
Obviously the terms Open and Free mean nothing to you, or your business!

Try killing plasmashell first, and then starting it. Use the following two commands in krunner (Alt+F2), to do that:

Code: [Select]
kquitapp5 plasmashell
kstart5 plasmashell

Hi guys,
Thanks for this fast replies, I tried both, but unfortunately I have no results,
Now I have this problem on my laptop computer as well, apparently just after having tried to set a different timezone....

Well,
I tried to create a dummy user account on my laptop, and it didn't work,
But, because the bug came after I tried to change the timezone, I removed /etc/localtime,
And it  works again, I'm gonna try this on my other computer tomorrow (finger crossed :3)
So, don't try to adjust your local time with KDE 5 as normal user :D
Cheers ! ;)
