Bug 403126

Application: ksysguard (5.14.4)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.20.0-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I had opened Ksysguard and scrolled to the bottom of the list to check if wineserver had been killed properly then tried to close it and I was alerted to a crash.

The crash does not seem to be reproducible.

-- Backtrace:
Application: System Monitor (ksysguard), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
