           Summary: Kontact crashed when Network Manager settings altered
           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: a.ball at ukoln.ac.uk


Application: kontact (4.4.9)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
For reasons I won't go into, I deleted the active wireless connection using the
Network Management plasmoid, with a view to recreating it. Kontact was running
at the time, and immediately after the connection was deleted, it crashed.

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