Sentry Crash Report:
Attachments: New crash information added by DrKonqi

Description Christian 2012-12-02 08:11:59 UTC 
Application: akonadi_imap_resource (4.9)
KDE Platform Version: 4.9.3
Qt Version: 4.8.2
Operating System: Linux 3.5.7-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

-- Information about the crash:
- What I was doing when the application crashed:
There was a popup informing me that the certificate to my IMAP SSL connection has expired. I clicked on Cancel. Then there was a popup asking whether I want to go to the account settings because there seems to be a problem with the password. I clicked on Cancel again. That causes this crash message to appear.
The first popup is shown every time, and when I click on the Cancel buttons, the crash always happens.
The crash also happens if, for another reason such as interrupted internet connection, the second popup (about going to the account settings) is shown and I click Cancel.

The crash can be reproduced every time.

-- Backtrace:
Application: IMAP-sähköpostipalvelin ESiOR OWA (akonadi_imap_resource), signal: Segmentation fault

New crash information added by DrKonqi

akonadi_imap_resource (4.10) on KDE Platform 4.10.00 "release 1" using Qt 4.8.4

- What I was doing when the application crashed: on a previous working imap(tls) offline account, change in the account the password to make it wrong.
with akonadi configuration, run the edit account, and let it failed the login. Cancel, re-edit by putting the right password.
Then I get the backtrace report.

server is dovecot + tls

Comment 4 David Faure 2013-02-17 21:02:34 UTC 
Git commit d82e4917f7286984bce16c2fa36ea4e9f6a24453 by David Faure.
Committed on 17/02/2013 at 21:54.
Pushed by dfaure into branch 'KDE/4.10'.

Fix crash due to dangling session pointer in m_pendingInitialSession.

This happens after disconnect() kills all sessions (e.g. due to losing
internet connection while the password dialog is up, or explicit toggling
of offline/online status, or due to the "SSL not supported").
