  Target Milestone: ---

Application: filelight (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.2.2-zen1-1-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.27.2 [KCrashBackend]

-- Information about the crash:
Unpredictably fill up /home and start filelight, then empty the recycle bin to
get a little space to start filelight again.
The qmlc file that caused the crash was found by setting the HOME environment
variable. The copy was compressed by `cmd` and encoded to base64.
