Application: kalendarac (1.0.0)

Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.13.0-28-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.1 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Nothing special, just browsing the web in Firefox. I woke up the laptop from standby a few minutes earlier. The KAlarmNotifier (or similar) window appeared with two event notifications that should have appeared while the laptop was in standby. Kalendar did not notify me about these two events. Instead, a notification about its crash appeared after a few minutes.

Note: this is likely the same bug as https://bugs.kde.org/show_bug.cgi?id=447836, but now in version 1.0.0

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Kalendar Reminders (kalendarac), signal: Segmentation fault
