Application: kontact (5.2.3)

Qt Version: 5.6.1
Frameworks Version: 5.25.0
Operating System: Linux 4.7.2-201.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"

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

Since the beginning of the month Kontact crashes often after minutes of running.

Kontact is called from the autostart feature of KDE during login procedure.

The crashes are repetitiv.

When switching to a newly arrived message in KMail Kontact crashes. This happens sometimes when switching between messages in different folders (no matter wether backup or other provider).

It happend the other day twice during writting mails. (There where just two mails to write late in the evening the night before.)

Kontact is running on a Fedora 24 x64. Installed from the repository packages

The crash can be reproduced every time.

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