Bug#1013220: org.kde.ksystemstats: (ksystemstats) of user 1000 dumped core. Stack trace of thread 33020: #0 0x000055ef3ffde3c0 n/a (n/a + 0x0)
Dear Maintainer,
I tried to have a look at this core file and it
provides below backtraces, one without and one with debug symbols.
This leads to this upstream bug, unfortunately without much responses:
https://bugs.kde.org/show_bug.cgi?id=428266
Kind regards,
Bernhard
