           Version: 4.14.3
          Platform: Mint (Ubuntu based)
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi

Application: kmail (4.14.3)
KDE Platform Version: 4.14.13
Qt Version: 4.8.6
Operating System: Linux 4.1.6-040106-generic x86_64
Distribution: Linux Mint 17.3 Rosa

-- Information about the crash:
- What I was doing when the application crashed:
Klicked the icon on the launcher bar to open Kmail.

The daemon is running in the background, as I get notifications of new mails.
I get mail from exchange server with davmail, this setup has been running with
success for a month now, before this happened.

The crash can be reproduced every time.
