Bug ID: 436707
Summary: System Monitor crashes when going from Overview >
Processes > back to Overview and then closing.
Product: plasma-systemmonitor
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: guimarcalsi...@gmail.com
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
Application: plasma-systemmonitor (5.21.5)
Qt Version: 5.15.2
Frameworks Version: 5.81.0
Operating System: Linux 5.4.0-72-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: KDE neon User Edition 5.21
-- Information about the crash:
- What I was doing when the application crashed:
I can reproduce the crash everytime. To reproduce it, open System Monitor (by
default it will be in the Overview tab), go to the 'Processes' tab, then
imediatelly go back to 'Overview' and close it. Upon closing, Dr. Konki will
pop-up telling an error has happened. The crash only happens when following
these instructions in the right order. No other tab triggers the crash.
Operating System: KDE neon 5.21
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.81.0
Qt Version: 5.15.2
Kernel Version: 5.4.0-72-generic

Processors: 4 × Intel® Core™ i5-6200U CPU @ 2.30GHz
Memory: 7,7 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 520
The crash can be reproduced every time.
