           Summary: crash on index (re)generation
           Product: kmail
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: bug-report mircea bardac net


Version:           Kmail coming with KDE 3.5.6 (using KDE Devel)
Installed from:    Compiled sources

KMail in KDE 3.5.6

My system froze once (unknown reason) and I had to reset - this bug might be related to the other bugs mentioning loss of data on system restart/crashing.

After the restart, Kontact (kmail) kept crashing, making me unable to read my mails. I suspected a problem with the index and deleted all of them. After more digging and starting Kontact with some mail folders moved.. I managed to track the misbehaving folder.

I also reproduced the crash by creating a new user, starting kontact, creating a dir witht the same name, stopping contact, moving the old dir contents in the newly created dir, restarting Kontact.

The buggy folder can be found here: http://mircea.bardac.net/temp/jdev.tar.gz

The backtrace of the crash is the following (not sure if it helps much):
