Description tuxsudo 2021-12-04 16:21:47 UTC

Application: plasmashell (5.23.4)

Qt Version: 5.15.2
Frameworks Version: 5.88.0
Operating System: Linux 5.15.6-hardened1-1-hardened x86_64
Windowing System: Wayland
Distribution: EndeavourOS
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
*Repost because previous bug report was marked as a downstream issue with Lightly, which may have been indicative of the theme I was using in the backtrace but switching to Breeze themeing I still have a the same problem, albeit behaviour slightly different now*
Using both Firefox and Brave browser with Plasma Integration Addon/Extension, playing media from a website with a self signed certificate causes a "Server Authentication" popup to showup and clicking any of the buttons will usually result in a plasmashell restart. Occassionally (Usually only the first time after a restart or session login) I can get it to show another popup after clicking "Continue" asking me if I want to ignore the certificate for this session or forever however none of the buttons work in that popup once again resulting in a plasmashell crash and restart. Clicking Details, Cotinue, or Cancel all result in a crash.

The Popup in Question says
"The server failed the authenticity check (192.XXX.X.XX).
The issuer certificate of a locally looked up certificate could not be found"
(Self signed Caddy certificate)

The crash can be reproduced every time.

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

I'll iterate that technically this is not a repost, I'm not just posting the same bug report but it is the same problem I am having but with a different backtrace using Breeze teeming so hopefully this helps, incase the previous backtrace was legitimately a Lightly issue.
