            Bug ID: 346257
           Summary: KMail fails to retrieve IMAP messages, then crashes
                    when restarting
           Product: kmail2
           Version: 4.14.1
          Platform: Debian stable
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: johannes.willkomm at gmail.com

Application: kmail (4.14.1)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.0 (jessie)

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

KMail failed to synchronize with IMAP servers and retrieve new messages.
Then, when I close KMail, do a killall kmail and restart KMail, it crashed

- Unusual behavior I noticed:

Since an update to a new kdepim-runtime package in my Debian Testing in last
autumn, I experience this problem

This happens sometimes but relatively often. In the other cases, Kmail starts
up but still does not retrieve the new messages. The only thing that helps is
stopping and restarting Akonadi

The crash can be reproduced sometimes.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
