Bug 462998

Application: plasma-discover (5.26.4)

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.3-x64v1-xanmod1 x86_64
Windowing System: X11
Distribution: KDE neon 5.26
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
When I open discover it says "The server failed the authenticity check (autoconfig.kde.org)" and "The issuer certificate of a locally looked up certificate could not be found". After looking into detail, the issuer in question has:
Common name for "R3"
Organization for "Let's Encrypt"
Country for "US"
Everything else is just empty

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
