SUMMARY

I have a weird problem with my nic which I believe causes ksysguard to crash. 

STEPS TO REPRODUCE
1. sometimes, my network stops working. 
2. This causes network manager to first come in "Limited connectivity" state
(first line in attached logs)
3. after that i usually unplug the network cable to see if it helps


OBSERVED RESULT
segfault
something like this (more context in attachment):

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: opensuse tumbleweed 20210128
(available in About System)
KDE Plasma Version: 5.20.5
KDE Frameworks Version: 5.78.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
I have a quite recent laptop model: Dell Latitude 5501. Network is problematic,
even on windows I sometimes have to unplug / replug the cable to regain network
access. Still, I believe ksysguard should not crash..?
