           Summary: Frequent kmail crashes when auto expire is used
           Product: kontact
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: mail
        AssignedTo: kdepim-bugs kde org
        ReportedBy: peter.soetens mech kuleuven be


Version:           unknown (using KDE 3.5.6, Kubuntu (edgy) 4:3.5.6-0ubuntu1~edgy1)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.17-10-generic

About 1-5 times a week, my kontact/mail usage crashes when I click on a message or push-down to a new one in one of my mail boxes. I believe this crash started to occur when I started using the 'Expire...' option on several local mailboxes. They are 'targets' for a filter for incomming mail. (filter puts the message in the mailbox, expire removes it).

This bug was present in most/all KDE 3.5 versions.

The backtrace is:
$ cat /tmp/kontact-crash.txt
