The Weather Report widget fails to get data of course, but it doesn't bring down all of Plasma. No VPN here, though. So it does seem like your VPN is the cause of this. |
Created attachment 187644 [details] Backtrace SUMMARY No actions were taken to cause crash other than booting my computer and logging in through SDDM to a wayland session. About crash: - Plasmashell crashes repeatedly and I'm left with a black screen and multiple crash dialogs. Applications still work and can be launched through a terminal or krunner, and I can drag windows around; however, my desktop widgets and panels don't appear. - Weather Report is using Environment Canada as source. Testing done: - Disabling Mullvad VPN services eliminates crashes. - Disabling the Weather Report system tray extension no longer crashes plasmashell. - Reinstalling Plasmashell and Mullvad does not fix crash. - Removing/Resetting configuration files for Plasma does not fix crash. Non-standard configurations: - Mullvad VPN is active from launch, although this often requires a disconnect and reconnect for internet to work. - Full-disk encryption, excluding /boot. The crash can be reproduced every time. STEPS TO REPRODUCE 1. Enable Mullvad VPN services (mullvad-daemon.service, mullvad-early-boot-blocking.service) 2. Enable Weather Report tray icon 3. Boot computer OBSERVED RESULT Plasmashell crashes repeatedly EXPECTED RESULT Plasmashell does not crash SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.18.0-3-cachyos KDE Plasma Version: 6.5.4 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.1 ADDITIONAL INFORMATION - I suspect this crash is caused by the weather report system tray extension not being able to connect to the internet.
