Sentry Crash Report:

Description Aroun 2021-06-09 14:44:59 UTC

Application: kontact (5.17.1 (21.04.1))

Qt Version: 5.15.3
Frameworks Version: 5.82.0
Operating System: Linux 5.4.0-74-generic x86_64
Windowing System: X11
Drkonqi Version: 5.22.0
Distribution: KDE neon User Edition 5.22

-- Information about the crash:
- What I was doing when the application crashed:
Clicked on the close window button
I think there where two kontacts instances open because I openend it twice. There was also a window asking for my name and email. So I closed one instance and all crashed

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
