Bug 450879

Application: plasmashell (5.24.80)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.11.0-40-generic x86_64
Windowing System: Wayland
Distribution: KDE neon Unstable Edition
DrKonqi: 5.24.80 [CoredumpBackend]

-- Information about the crash:
- What I was doing when the application crashed:
The list of favorites apps of my kickoff has an icon created with kmenuedit to run Firefox natively on Wayland.
Plasma crashes every time I click on it. No crash occurs when I click on other favorites not created with kmenuedit.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
