Application: kmail (5.8.2)

Qt Version: 5.11.1
Frameworks Version: 5.48.0
Operating System: Linux 4.15.0-29-generic x86_64
Distribution: KDE neon User Edition 5.13

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

I've started Kmail after an system reboot. Before the reboot I've installed system updates.

After the update Kmail have shown some strange behaviour. If I tried to open an mail
it took a couple of seconds to show the window and if I hit reply, it took up to a minute until
the reply window came up. Not sure if this is related but it's why I did the restart at this point.

The crash can be reproduced every time.
