Description Kwanza.Pili 2019-04-02 15:21:19 UTC

Application: kmail (5.10.3)
 (Compiled from sources)
Qt Version: 5.12.2
Frameworks Version: 5.56.0
Operating System: Linux 4.19.23-1.1 x86_64
Distribution: "openSUSE Leap 15.0"

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

Every time I close kmail, I get this error "application terminated unexpectedly" I think this is caused by some code deleting data too early (as suggested by some QT developers).

The crash can be reproduced every time.

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