Application: kontact (5.12.0)

Qt Version: 5.12.3
Frameworks Version: 5.61.0
Operating System: Linux 5.0.0-25-generic x86_64
Distribution: KDE neon User Edition 5.16

-- Information about the crash:
- What I was doing when the application crashed:
I wasn't doing anything. The crash happens by itself a few minutes after I open kontact, no matter what tab I have open. I have already tried uninstalling and reinstalling to no effect. It doesn't happen with kmail, but I haven't tested with other programs in isolation yet.

The crash can be reproduced every time.

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