Description Marek McGann 2008-10-07 19:35:01 UTC

Version:            (using KDE 4.1.2)
OS:                Linux
Installed from:    Ubuntu Packages

When editting an event to remove an attendee, korganizer (and kontact) crashes when either the Apply or OK buttons are pressed.

This is the case whether or not the event recurs, and whether or not they are the only listed attendee.

Comment 1 Christophe Marin 2008-11-18 23:35:05 UTC

Are you able to reproduce this crash ? If yes, please install the kdepim-dbg package and provide a backtrace when Korganizer crashes.

Comment 4 Allen Winter 2008-11-20 13:55:33 UTC

SVN commit 886882 by winterz:

when changing the Attendee list, let's not overload the Incidence
Observer about it. 

This fixes a crash when removing Attendees.
Well, at least it does in my testing.  More testing appreciated.
I'll close until someone reports that they can still make it crash.

I am able to reproduce this bug on 4.1.3 (ubuntu intrepid-backports). Also I see the issue with to-do entries. My backtrace follows.
