Bug 504756

Application: plasma-systemmonitor (6.3.5)

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.0
Frameworks Version: 6.14.0
Operating System: Linux 6.14.8-cachyos1.fc42.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)"
DrKonqi: 6.3.5 [CoredumpBackend]

-- Information about the crash:
I entered plasma systemmonitor, visited the processes tab and sorted backwards by memory
strangely it appears many processes consume "-1 KiB" ram, and the data for many processes is not filled in
sometimes it occurs immediately, sometimes after a few seconds and after clicking on processes, sometimes not at all (but it does hang for quite a while after interacting with the ui)  
the app crashes with a Segmentation fault

The crash can be reproduced sometimes.
