           Summary: KMail crash while shutdown
           Product: kmail2
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mprizee at laposte.net


Application: kmail (1.13.6)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.2
Operating System: Linux 2.6.37-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I asked for a system shutdown (from the kde menu), then Plasma and all the
other apps disappeared, and Dr.Konqui opened, about this crash of KMail.
- Unusual behavior I noticed:
It is maybe not linked, but KMail took 90% of the CPU sometimes (today for
instance) so I kill the process and I run KMail again.
(And at first KMail start of the session, Akonadi seems to be started with it,
and it complain about some errors in log files, pressing "Close" makes KMail to
exit)

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
