Bug 439314

Application: plasma-systemmonitor (5.21.4)

Qt Version: 5.15.2
Frameworks Version: 5.80.0
Operating System: Linux 5.11.0-22-generic x86_64
Windowing System: X11
Drkonqi Version: 5.21.4
Distribution: Ubuntu 21.04

-- Information about the crash:
- What I was doing when the application crashed:
1) Create new page
2) Add "Individual Core Usage" to it
3) Change "Display Style" to "Process table"
4) Change "Display Style" to "Application table"
5) Crash :(
- It also works the other way around:
1) Create new page
2) Add "Individual Core Usage" to it
3) Change "Display Style" to "Application table"
4) Change "Display Style" to "Process table"
5) Crash :(
And probably with other widgets etc.

The crash can be reproduced every time.

-- Backtrace:
Application: System Monitor (plasma-systemmonitor), signal: Segmentation fault
