Bug 421845

Application: plasmashell (5.18.90)

Qt Version: 5.14.1
Frameworks Version: 5.70.0
Operating System: Linux 5.6.12-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
Logged out of Plasma, after logging back in an error would show in the system tray showing a Plasma crash. However, there was no visible crash or any other strange errors, just the notification in the system tray.

- Custom settings of the application:
Updated to Plasma version 5.18.90 through KDE's extra repositories for OpenSUSE Tumbleweed

The crash can be reproduced every time.

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