           Summary: KMail crash while attemping to load POPed email from
                    Akonadi
           Product: kontact
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: clark at exiter.com


Application: kontact (4.6.0)
KDE Platform Version: 4.6.4 (4.6.4) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r2 x86_64
Distribution: "Gentoo Base System release 2.0.2"

-- Information about the crash:
I recently upgraded to KDE 4.6.4 (with KDE PIM 4.6)  on Gentoo and migrated my
email to Akonadi. I've been able to retrieve my email for a couple of days, but
today KMail started crashing each time it attempted to obtain mail from the
Akonadi store.

The crash can be reproduced some of the time.

-- Backtrace:
