           Summary: When accepting a change of a shared event (received
                    via e-mail), Kontact crashes
           Product: kontact
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: matija at suklje.name


Application: kontact (4.7.0 )
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.39-gentoo-r3 x86_64
Distribution: "Gentoo Base System release 2.0.3"

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

In KDEPIM 4.6.0 or 4.6.1 I had accepted an invitation to a shared event — an
event that was organised by someone else and I was one of the attendents. When
I clicked "I accept" on the automated invitation e-mail in KMail, the event was
added to KOrganiser and all was well :)

Then I upgraded to KDEPIM 4.7.0 and I received another automated e-mail with a
change that the event organiser made (change the date, time and turned off the
recurrence). When I clicked "I accept" or "Show in Calendar", Kontact crashed.

The crash can be reproduced every time.

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