            Bug ID: 496471
           Summary: Systemsettings crash when selecting "More information
                    about my system"
    Classification: Applications
           Product: systemsettings
           Version: 5.27.11
          Platform: Kubuntu
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: [email protected]
          Reporter: [email protected]
  Target Milestone: ---

Application: systemsettings (5.27.11)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-49-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.1 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
I opened the window "system settings", in the column I chose "About this
system" and in this window I cklicked on the button "show more informations".
When I cklicked on that button, "system settings" crashed the first time on my
system. 
There is a night color problem, I assume. My system is Kubuntu 23.04 LTS in
x11. Color temperature (of night color mode) is constantly switching back and
forth between two different color temperatures every few seconds, no matter if
night color mode is enabled or disabled. When the crash of "system settings"
happened, night color was indeed enabled, but it wasn't supposed to be active
at the time of the crash, because I've chosen "Enable night colors at custom
times" and the time of day, that I set up in night colors, wasn't already
reached.
I had several applications (Brave browser roughly not more than 3-4 tabs
opened, Thunderbird, system settings, Terminal) opened at the time of the
crash, which is not supposed to be that unusual, i would guess. My hardware is
powerful enough to run Kubuntu with several windows opened, I think (Intel
i5-2500 3,3 GHz cpu, 8 GB RAM, NVidia GeForce GTX 970)

The reporter is unsure if this crash is reproducible.
