            Bug ID: 296692
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Kontact crashes when logging out
    Classification: Unclassified
                OS: Linux
          Reporter: iskendar at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: general
           Product: kontact

Application: kontact (4.8.0)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.0.0-16-generic-pae i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
Logging out of kde after it started with an activity manager crash.
- Unusual behavior I noticed:
Kde started with virtuoso hogging the cpu, plasma desktop/kwin lagging
(dragging windows left afterimages for a minute or so) and the activity manager
died. 
Possibly related to some nepomuk issues about indexing mails, as discussed on
the forum.

The crash can be reproduced some of the time.

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