Bug 473034

Application: dolphin (23.04.3)

Qt Version: 5.15.10
Frameworks Version: 5.108.0
Operating System: Linux 6.4.7-zen1-3-zen x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.27.7 [KCrashBackend]

The part that causes the crash is the "=" sign in the Exec parameter.
The crash also happens when opening properties from Plasmashell, crashing the entire desktop.

The crash can be reproduced every time.
