-- 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
