Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description Jonathan Marten 2017-11-21 09:40:36 UTC 
Application: kmail (5.6.80)
 (Compiled from sources)
Qt Version: 5.9.3
Frameworks Version: 5.40.0
Operating System: Linux 4.12.12-gentoo x86_64
Distribution (Platform): Gentoo Packages

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

The crash happens if KMail is quit while some network jobs are in progress.

What seems to be happening in the backtrace is that stopping the Akonadi jobs tries to display a message in the status bar, which crashes because the KMainWindow and all of its associated widgets are already in the process of being destroyed.

The crash can be reproduced sometimes.

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

New crash information added by DrKonqi

kmail (5.7.1) using Qt 5.9.4

- What I was doing when the application crashed:

I closed KMail after retrieving emails and it crashed a while after being closed.
