- 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.

Comment 1 davidblunkett 2016-09-14 07:09:23 UTC 
I have a similar problem in 5.1.3.

kmail hangs "checking folder contents" - if I quit and restart I get a crash report (seg fault) and a new kmail, kmail remains useless (checking folder contents) until I log out and log back in (which I guess points to a backend failure of some sort).

This has occurred a 1/2 dozen times in the last 48 hours so it is quite irritating!

In one instance upon restart I appeared to have lost all email, IMAP and local folders - a message popped up and disappeared before I could read it and my email reappeared 20 minutes later.
Comment 2 squan 2016-10-13 11:34:29 UTC 
Since recently I'm having the same problem on openSUSE Leap 42.1 with updated Qt-5.7.0 and  packages
   kmail5 16.04.3
   akonadiserver 16.08.1.
from http://download.opensuse.org/repositories/KDE:/Applications/openSUSE_Leap_42.1/

Running kmail from a newly created user account shows the same error, hence this is not a problem of a broken user configuration (in accordance with https://bugs.kde.org/show_bug.cgi?id=358145)

Note: The KDE crash agent correctly proposed my problem as duplicate of this bug, but it did not allow to proceed and append this information here.
