Bug 422780

Created attachment 129220 [details]
New crash information added by DrKonqi

plasmashell (5.19.0) using Qt 5.14.2

- What I was doing when the application crashed:
I was configuring the memory usage widget and after I changed the style of the display from Pie chart to line chart and hit apply, Plasma crashed abruptly. I tried to to reproduce the crash and have observed that Plasma crashes sometimes(but not every time) when I right click on the widget and click Configure... If it manages to get past that, then it crashes when I try to apply my settings. So far, I observed it for the Memory Usage widget only.

- Unusual behavior I noticed:
The Memory Usage widget wasn't displaying anything and was totally blank which is why I tried to configure it in the first place. Also, if it helps, the configure widget icon has the following unusual text(with matching case,symbols and spacing): &Configure System monitor Sensor

My Plasma also crashed after trying to configure Widgets, and Widgets were empty, such as using CPU and Network speed, tried to add other Widgets, such as Disk Usage and Hard Disk Activity, they were empty too, tried to change themes - it didn’t help, it’s on OpenSUSE Tumbleweed with the updated Plasma 5.19. Update: today a system update has arrived, and some Widgets display has started working, but not all styles work correctly, and Plasma also crashes sometimes when trying to configure them ...

I will add more information on the situation today. I have four widgets on my desktop: Clock, Weather, CPU Usage, Network Usage. CPU Usage widget (line chart) does not work correctly, namely, after turning on the PC, only the initial state of the widget is displayed and it is static, but if I only make Log out and then Log in again, this widget starts working properly.

I'm no longer on openSUSE tumbleweed with KDE. I'm on Void Linux with
Cinnamon.

Scary backtrace not obviously in any KDE code. :/

No reports from Plasma 5.20 or newer, and none within the past 13 months; looks like this was fixed somehow, probably in 5.20.

Sorry to report but me on my Manjaro (testing) KDE Plasma and my friend who uses Manjaro (stable) KDE Plasma have this issue. It mostly crashes when I right-click on desktop and press "Configure Desktop and Wallpaper...". I ran "sudo systemctl -f" before I tried reproducing the bug. Plasmashell core dumped but I don't know how to add the output here without making my reply so long.

My
KDE Plasma Version: 5.24.3
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Kernel: 5.16.17-1-MANJARO (64-bit)
Graphics Platform: X11

It's almost certainly a different issue, and anyway we'd need a backtrace of the crash to be sure. Can you open a new bug report and make sure to include a backtrace of the crash?
