Description Vin 2024-11-19 19:14:33 UTC

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.

The crash backtrace indicates that the problem is in the Nouveau graphics drivers. Please read https://nouveau.freedesktop.org/Bugs.html and submit a bug report for the Nouveau developers. Thanks!
