Bug 444909

Application: kontact (5.18.2 (21.08.2))

Qt Version: 5.15.2
Frameworks Version: 5.87.0
Operating System: Linux 5.14.6-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.2 [KCrashBackend]

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

1. I opened the calendar properties in KOrganizer and changed the URL. The new URL pointed to the very same physical destination, but it was an external address to the same DAV resource.
2. I modified the look-back interval from 2 years to infinite (so I turned off the limitation).
3. I clicked OK.

First, KOrganizer shown a random calendar (or perhaps a to-do) entry for today and some seconds later it crashed completely.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = <optimized out>}
