            Bug ID: 373607
           Summary: KMail crash on close
           Product: kmail2
           Version: 5.2.3
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: honggoff at gmx.ch
  Target Milestone: ---

Application: kmail (5.2.3)

Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.8.0-30-generic x86_64
Distribution: Ubuntu 16.10

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

I closed the main window of KMail. After the window closed, the crash reporting
assistant appeared, indicating that the program has caused a segmentation
fault.

This is not the first time this crash has happened. So far I didn't notice any
data loss or other adverse effects. However, it does not happen every time I
close the program.

The crash reporter could not find debugging symbol packages for all involved
libraries. I would be happy to install them manually if that is useful for
future crashes.

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".
