Bug 492015

Application: plasmashell (6.1.4)

Qt Version: 6.7.2
Frameworks Version: 6.5.0
Operating System: Linux 6.8.0-40-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 6.1
DrKonqi: 6.1.4 [CoredumpBackend]

-- Information about the crash:
IWhen I am using any application, whether accessing the internet, listening to music, or running Java desktop applications (such as SweetHome3D), the problem occurs that the icon bar (Task Manager) keeps closing unexpectedly, only to be displayed again seconds later.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: plasmashell (plasmashell), signal: Segmentation fault
