Description kwasha.spam+kde 2022-08-07 22:49:14 UTC 
Application: plasmashell (5.24.4)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.15.0-45-generic x86_64
Windowing System: X11
Distribution: Ubuntu 22.04.1 LTS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Trying to set the weather tray (searching for location) but DNS was down (firewall)

- Custom settings of the application:
I upgraded from 21.10 and my firewall allowances are based on interface name... which changed during upgrade.

The crash can be reproduced every time.

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