           Summary: imap handler crashed after resuming from sleep where
                    the imap server wasn't available
           Product: Akonadi
           Version: 4.7
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: IMAP resource
        AssignedTo: ervin at kde.org
        ReportedBy: tubaman at fattuba.com
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:  I put the laptop to sleep at
work where I have access to my imap server.  I resumed at home where the imap
server is unavailabled.  The imap handler crashed.  Instead of crashing the
imap handler should fail gracefully.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Work of type IMAP E-Mail Server (akonadi_imap_resource), signal:
