           Summary: Conflict Resolution
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: momix at mcgrew-fam.net


Application: kontact (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed: I had thousands and thousands
of SPAM emails. I'm using Spamassassin to help filter them. I started getting
thousands of kontact conflict resolution notices. This began happening after I
allowed some updates to d/l and install yesterday. Otherwise, my kubuntu system
was completely up-to-date. I tried to close kontact normally and it crashed. 

- Unusual behavior I noticed: Thousands and thousands of kontact resolution
dialog boxes started popping up.

The crash can be reproduced every time.

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