Application: systemsettings5 (5.20.5) Qt Version: 5.15.2 Frameworks Version: 5.78.0 Operating System: Linux 5.10.13-lqx2-fire x86_64 Windowing system: X11 Distribution: "Arch Linux" -- Information about the crash: - What I was doing when the application crashed: I was trying to change my default browser from Firefox to Chromium. When I search for Default Applications in the Settings and clicked on it, a crash took place. I cannot find this setting without searching for it by the way. - Custom settings of the application: I have 2 browsers. One is native Chromium and the other is Flatpak Firefox. The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings5), signal: Segmentation fault [KCrash Handler] #4 0x00007feb0333d8b4 in KService::storageId() const () from /usr/lib/libKF5Service.so.5 #5 0x00007feabf08aa37 in ??

Any chance you can compile with them, reproduce the crash, and attach a new crash log? Thanks. Here's arch's documentation regarding how to do this: https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces
Thank you for your reply. I compiled systemsettings with the debug and !strip options.

The update to version 5.21.0 seems to have fixed this problem. Thank you for responding to my bug report Nate.
Glad to hear it!
