Description Elias 2022-07-14 14:25:51 UTC

Application: plasmashell (5.25.3)

Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.15.0-41-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.3 [KCrashBackend]

-- Information about the crash:
I am connected to a LAN connection and to a Wifi connection. When I open the network panel in the taskbar and click at the arrow next to each available connection, it firsts expands the box of the specific network but with nothing in it. Then my whole PC freezes for a few seconds. After that The network panel gets white (I am using dark mode) and blurred out. Then Plasma chrashes and the taskbar disappears, after a further few seconds, it's there again.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
