Systemsettings segmentation fault

Right click networks system tray icon > configure networks connection > click firewall (I do not have one installed) > click proxy > application crashes
Has to be done in that order (and I suspect with missing firewall)
Clicking proxy without first clicking firewall correctly displays the proxy settings instead of crashing.

I do not have debugging symbols installed, but it seems easy to reproduce.

if that is so then it could be an issue with plasma-firewall. I don’t have that red warning and I assume that’s because the firewall I had and removed for testing your case left some configuration file behind which would be normally read but can’t be when no firewall is installed in the first place, thus maybe consuming all that CPU. But that’s just speculation, a dev should look at the crashdump, I see some Qt6Core stuff again and deleteLater() that look familiar to me i.e. relevant to those crashes of the System Monitor when switching tabs/Discarding Changes/Showing Details Sidebar and were fixed already for 6.1 or something.

Are you using latest Plasma settings?

Well I installed a firewall since interests was not shown so now I can no longer help with testing the issue.

But there IS a bug with this on arch stable.
Lucky it was just looping ONE core and not all.

I can reproduce.

Thanks for debugging this, I added the relevant information you provided to the bug report: 485101 – Systemsettings crashed after viewing Firewall settings then switching to other category
