Description Martin Bednar 2012-07-23 10:48:26 UTC 
Application: akonadi_imap_resource (4.8)
KDE Platform Version: 4.8.97
Qt Version: 4.8.2
Operating System: Linux 3.4.5-pf-PF x86_64
Distribution (Platform): Gentoo Packages

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

Started up KDE session, with akonadi starting automatically. The imap resource encountered an error : Login failed, server replied: A000002 NO Lookup failed v18if12417105wed.180
, showed a dialog allowing changing the config or trying again or canceling. Any action taken results in this crash, every time.
Easiest way to reproduce is restarting the akonadi server. This might be due to a network configuration problem, however the resource shouldn't crash.

The crash can be reproduced every time.

-- Backtrace:
Application: GMail de type Serveur de courriels IMAP (akonadi_imap_resource), signal: Segmentation fault

Comment 1 David Faure 2013-03-03 13:04:45 UTC 
commit 5c4a1fea0347e7536ec2c03aebb421536daba441
Author: David Faure <faure@kde.org>
Date:   Sat Mar 2 14:59:19 2013 +0100

    Fix crash in SessionPool::onPasswordRequestDone, again due to m_pendingInitialSession.
    
    It could become dangling in the following case:
    - wrong imap password, error dialog shows up, leave it up
    - wait for connection to drop (idle timeout, or maybe due to losing network altogether)
    - resource reconnects, wrong password still, error dialog show up.
    When closing them both, the 2nd one ends up in SessionPool::onPasswordRequestDone with
    a dangling m_pendingInitialSession.
