           Summary: Akonadi IMAP Agent crashes upon toggling it "offline"
           Product: Akonadi
           Version: 4.7
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: IMAP resource
        AssignedTo: ervin at kde.org
        ReportedBy: greve at fsfe.org
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Application: akonadi_imap_resource (4.7)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.6-1.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
My Akonadi IMAP agents regularly hang throughout the night, e.g. because the
connection to the IMAP server got dropped temporarily. The workaround for this
is to toggle it offline and then turn it back online. When turning it offline,
it crashes every single time for the same accounts, see backtrace. 

Sometimes Akonadi then manages to restart the agent, sometimes I have to log
out/back in at the very least.

The crash can be reproduced every time.

-- Backtrace:
