           Summary: Kmail crashes while adding/removing old emails to/from
                    inbox
           Product: kontact
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: abenson at its.caltech.edu


Application: kontact (4.7.3)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.i686.PAE i686
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed: Attempting to delete an
e-mail. When I do anything (get new mail, delete mail, move an email to a
diffrent folder), KMail seems to reload 30-40 old emails (ones which I've
either deleted before or moved to other folders) back into the inbox. These
then gradually disappear from the inbox again (although not always). Usually
this just slows down KMail but it eventually does what I asked it, but some
times it causes a crash.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
