Description senemux 2019-06-21 06:42:10 UTC

Application: plasmashell (5.16.1)

Qt Version: 5.12.4
Frameworks Version: 5.59.0
Operating System: Linux 5.1.12.a-1-hardened x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

Clicked on application launcher, then closed it shortly after

- Custom settings of the application:

Panel: Application launcher, icon only task manager, grouping plasmoid (CPU load monitor, memory status, network monitor, hard disk I/O), system tray, date and time

Desktop: No widget, wallpaper type is "image". 

Theme: Sweet, but with Breeze window decorations.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
