Description Jason Playne 2022-02-09 01:02:41 UTC
Application: plasmashell (5.24.0)

Qt Version: 5.15.3
Frameworks Version: 5.90.0
Operating System: Linux 5.16.7-051607-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.0 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I upgraded to the latest 5.24.0 release and walked away from my PC for 30-40 minutes - enough time for the power management to turn my monitor off.

I came back to my computer and started using it and noticed the time was wrong,. I right with date/time taskbar applet and chose adjust date/time - i noticed the time was correct in there.

I ran ntpdate-debian on the cli, the applet did not update its time shown.

Launched applications did not appear on the task bar (spotify in my case)

In a terminal I ran plasmashell --replace &

back to a working task bar / time applet

The reporter is unsure if this crash is reproducible.

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