           Summary: kmail crashed when "compact folder" used on folder
                    with a lot of mail
           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: xgeorge at seznam.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 2.6.31-22-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
- kmail, latest updates of my distro applied today (but not sure if this is the
cause of this bug, because I did not tried to use "compat folder" before)

how to reproduce:
- open kmail
- select the folder with a lot of mail, in my case there are 77617 messages,
26128 of them unread
- wait until content of folder is loaded
- right-click the folder and select "compact folder" from the menu
- HDD starts gargle now, but after about 10seconds it stop and then after a
second kmail crash
- may be reproduced everytime (tried 4x)
