            Bug ID: 389670
           Summary: CalDav crash when deleting altered instance of
                    recurring event
           Product: Akonadi
           Version: 5.5.2
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: DAV Resource
          Assignee: kdepim-bugs at kde.org
          Reporter: kde at m-pixel.com
  Target Milestone: ---

Application: akonadi_davgroupware_resource (5.5.2)

Qt Version: 5.6.2
Frameworks Version: 5.32.0
Operating System: Linux 4.4.112-2.gaf1ac1a-default x86_64
Distribution: "openSUSE Leap 42.3"

-- Information about the crash:
- What I was doing when the application crashed:
1. I added a new CalDAV account (Fastmail to be exact)
2. I explored the interface, and added a journal entry to see how that worked
3. I assigned colors to a few of the calendars
4. I selected an event from the Week view; this event was an instance of a
recurring series, one which I had modified to be on a Wednesday at 10am instead
of the usual Tuesday at 9am
5. I pressed the delete key. A confirmation dialog appeared, asking if I was
sure that I wanted to delete the event. I thought it was strange that it didn't
ask me if I wanted to delete the whole series, or just the one occurrence, but
I went ahead and allowed it.

- Unusual behavior I noticed:
Immediately after confirming the deletion, a notification appeared regarding a
CalDAV related service crashing. Then, the event reappeared as its typical
Tuesday @ 9am.

-- Backtrace:
Application: DAV groupware resource (akonadi_davgroupware_resource), signal:
Segmentation fault
