Bug 479797

Application: systemsettings (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-13-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
I installed Viber from Flatpak. If try to add it to Autostart section of System Settings, nothing strange happens. But when restart the system, Viber doesn't start up for some reason. After I opened Autostart and tried to look inside the added shortcut by clicking edit button, the System Settings window crashed. This happens every time! I looked into stacktrace and didn't find any valuable info there, cause the tracing only indicated the line positions of the respective *.so libs in the stack! No any additional textual info or something!

I suspect, that crashing is caused due to the parsing complications of the command-line... Here it is from viber.desktop file:

Exec='/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=viber com.viber.Viber'

The same thing occurs for similar *.desktop files, that have more complex command lines... so the problem is more global.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
