Fri Apr 23 14:30:17 BST 2010

https://bugs.kde.org/show_bug.cgi?id=235176

           Summary: Kmail always segfaults after startup (using IMAP)
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: pavel.krc at mensa.cz

Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
After starting Kmail (with 3 online IMAP accounts), Kmail always ends with a
segfault after ~ 2 secs (probably at opening a folder or message). I'm sorry
that I have absolutely no time to study the backtrace at the moment, I will
provide further details later.
