            Bug ID: 425872
           Summary: Kontact crashes when accepting a delegated invitation
           Product: kontact
           Version: unspecified
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: kdepim-bugs at kde.org
          Reporter: sven.eden at gmx.de
  Target Milestone: ---

Application: kontact (5.15.0 (20.08.0))
 (Compiled from sources)
Qt Version: 5.15.0
Frameworks Version: 5.73.0
Operating System: Linux 5.7.18-gentoo x86_64
Windowing system: X11
Distribution: Gentoo/Linux

-- Information about the crash:
- What I was doing when the application crashed:
A collegue delegated an invitation for a zoom meeting to me. When I press the
"Accept" button, kontact crashes immediately.

Important: Kontact works perfectly fine on any of the invitation response
buttons in any invitation that got directly sent to me. This is the only case
where it crashes. So I daresay the delegation has something to do with it.

Some Background: The calendar used is an Exchange Calendar on an on-premise
Exchange 2013 server, and is connected using CalDav over the latest version of
davmail.

I have searched for duplicates, but all DrKonqi showed me where about other
areas than this. So hopefully I didn't miss _the_ relevant report I should have
latched on.

The crash can be reproduced every time.
