           Summary: Kontact/Kmail crashes when jumping to next unread
                    message during mail update and filtering
           Product: kontact
           Version: 4.7.1
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: andreas.karrenbauer at uni-konstanz.de


Application: kontact (4.7.1)
KDE Platform Version: 4.7.1 (4.7.1) "release 8"
Qt Version: 4.7.4
Operating System: Linux 3.0.4-43-desktop x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I have about 5000 mails in a local mail folder (from a POP3 account) that are
automatically filtered and organized in several subfolders. If I press the
update button, I can see the new mails comming in the base folder and then they
are distributed to the corresponding subfolders. I can watch this process
because all this does happen very slowly, so that I can even select  an unread
message in the base folder before it gets moved away by the filter. I assume
that my interaction during the mail update and filtering caused an undefined 
state that lead to the crash.

-- Backtrace:
