Application: kmail (5.5.1)

Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.4.0-78-generic x86_64
Distribution: KDE neon User Edition 5.9

-- Information about the crash:
- What I was doing when the application crashed:
After a time, Kmail stops displaying mail (the message pane just shows "Retrieving folder contents. Please wait".) Restarting kmail sometimes helps. So I quit kmail using Ctrl-Q and the crash happend.

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".
