Description Patrick Silva 2018-01-31 15:00:40 UTC 
Crash reproducible on Arch Linux (plasma 5.12 beta) and neon dev unstable.

start Wayland session
open "connections"
back to all settings and reopen "Connections"
Wayland session crashes, my system goes to login screen or I get a black screen without cursor and I need to force my computer to restart.
Comment 1 Martin Flöser 2018-01-31 17:27:45 UTC 
Doesn't crash on my neon dev unstable.

Can you get a backtrace?
Comment 2 Patrick Silva 2018-01-31 17:35:23 UTC 
If you give me detailed instructions, I can. 
I dont know to generate backtrace when the whole session crashes.
Comment 3 Patrick Silva 2018-02-03 23:28:51 UTC 
another way to reproduce wayland crash using system settings on Arch and neon dev unstable

start Wayland session
open system settings
open "disolay and monitor"
back to all settings and reopen "display and monitor"
Wayland session crashes, my system goes to login screen or I get a black screen without cursor and I need to force my computer to restart.

Nope I'm unable to reproduce. I think this is the same as bug #389231
Comment 5 Patrick Silva 2018-02-04 14:53:18 UTC 
Thank you Martin.

I just found other ways to reproduce the crash
open system settings > "display and monitor"
back to all settings, open "startup and shutdown" or "workspace theme" or "application style > window decorations"

It's probably all modules which have a nested QtQuick based KCM.
Comment 7 Martin Flöser 2018-02-04 16:02:26 UTC 
I dare to mark as duplicate. I just created a patch, so we will soon see whether this fixed the problem and was truly the same.

*** This bug has been marked as a duplicate of bug 389231 ***
Comment 8 Patrick Silva 2018-02-08 20:20:46 UTC 
cannot reproduce the crashes on neon dev unstable anymore.
Thank you Martin.
