Application: plasmashell (5.24.4)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-46-lowlatency x86_64
Windowing System: X11
Distribution: Ubuntu 22.04 LTS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

I have experienced the crash multiple times over the past week or two. Using a browser(any of 3) causes the crash. 
- Unusual behavior I noticed:
Today I noticed that the browsers are taking the memory usage from 1.5GiB of 3.8 to 3.5/6GiB of 3.8. After having had multiple crashes I left the System Monitor open behind by work. On this last occasion the machine had been idle on waking I launched Opera and I saw the Memory usage leap and multiple write attempts to the harddisk could be heard. I get the same crash with Firefox and Vivaldi.

Not running browsers seems to keep the machine stable.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
