Bug 435598

Application: plasmashell (5.21.3)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.3.18-lp152.66-default x86_64
Windowing System: X11
Drkonqi Version: 5.21.3
Distribution: "openSUSE Leap 15.2"

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

Logged in via SDDM, Plasma booted up normally. After leaving the desktop for about 3 minutes, Plasma suddenly crashes and restarts immediately afterwards. This is NOT reproduceable on my end.

- Custom settings of the application:
I have the System Monitor widget (CPU,RAM,NETWORK), desktop icons enabled, Global Menu Applet, Icon-only Task Manager.

Please note that I'm using OpenSUSE Leap 15.2 Argon, running the latest KDE releases (as of the time of writing.)

The reporter is unsure if this crash is reproducible.

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