Sentry Crash Report:

Description Aaron Williams 2020-01-25 04:00:40 UTC 
Application: kontact (5.13.1 (19.12.1))

Qt Version: 5.14.0
Frameworks Version: 5.66.0
Operating System: Linux 4.12.14-lp151.28.36-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.1"

-- Information about the crash:
- What I was doing when the application crashed:

When I attempted to fill in a previously used email address while writing an email, KMail crashed as it usually does. However, when I attempt to restart it it crashes immediately when it attempts to re-open the draft email I was typing. I have already reported the other crash (see bug# 416288 https://bugs.kde.org/show_bug.cgi?id=416288 ). The crash dump in this case is different, however.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Please update your system.
The libQt5Core5 package was corrupted in the KDE:Qt5 repo and caused similar
