            Bug ID: 411791
           Summary: KMail crashes upon closing
           Product: kmail2
           Version: 5.7.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: nospam.hoefling at arcor.de
  Target Milestone: ---

Application: kmail (5.7.3)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.0.0-25-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

-- Information about the crash:
- What I was doing when the application crashed: Checking mail, KMail was
hanging with "Updating folder". The crash occurred upon closing KMail via the
systray icon (Quit, Ctrl-Q).

I have 2 IMAP accounts and one POP3 account. Because of the very slow "Updating
folder" I recently switched to store mails locally as well. Similar crashes
happened before as well.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
