           Summary: Crash at start of KMail
           Product: kmail
           Version: 1.13.2
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: libe4 at free.fr


Application: kmail (1.13.2)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Each time i am trying to launch a new Kmail instance, it crashes with the same
stack trace.

My Kmail is set up with four accounts (2 IMAP - ISP + Gmail, 1 POP, 1 Live
Mail).

Nevertheless, I have good reasons to think the problem is related to my Live
Mail account. Sometimes, on this account, Kmail downloads my last received
message again (it then appears twice in my Live Mail inbox).

Thank you for studying the case.
Regards.


The crash can be reproduced every time.

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