            Bug ID: 356508
           Summary: Kontact crashes when requesting close
           Product: kontact
           Version: unspecified
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: mark at vowleyfarm.co.uk

Application: kontact (4.14.10)
KDE Platform Version: 4.14.14
Qt Version: 4.8.6
Operating System: Linux 4.2.6-201.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:

Closing Kontact (using close icon at top right of window) because it seemed to
have gone out of control. It was using around 50% cpu most of the time without
any visible cause.

- Unusual behavior I noticed:

A very (very) large number of emails appear as "popup notes" in the "overview"
section of Kontact, although they don't appear in the popup notes section.
I was looking for a way to remove them, until Kontact seemed to go wild.

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