Description Valtteri Tarvainen 2019-08-03 07:54:54 UTC

Application: plasmashell (5.16.4)

Qt Version: 5.12.3
Frameworks Version: 5.60.0
Operating System: Linux 5.0.0-23-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:
I just booted KDE neon and the Plasma desktop kind of flashed and the crash handler notification appeared. 

(I thought that even though it didn't cause me noticeable problem, it would be good to share this info.)

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

New crash information added by DrKonqi

plasmashell (5.16.4) using Qt 5.12.3

- What I was doing when the application crashed:
Once again I booted the KDE Neon and the Plasma Desktop crashed
- Unusual behavior I noticed:
Some time ago, I had needed to add myself to usergroup "kvm" for virtualization to work correctly. While I solved that problem, I made another one by I using usermod -G (or -g) and removed myself from every other group than kvm, then I added myself back to groups I thought my account previously was part of via root shell from recovery mode.

- Question regarding to user groups and suggestion:
Do I need to be part of some group to be able to use Plasma correctly? if so, it would be nice to have a notification telling me that my permissions are not correctly set.

Seems to be a duplicate of https://bugs.kde.org/show_bug.cgi?id=411995. Did you launched with "startx" too?
