            Bug ID: 447836
           Summary: Kalendar event notification crashes
           Product: kde
           Version: unspecified
          Platform: Neon Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: florian-edelmann at online.de
  Target Milestone: ---

Application: kalendarac ()

Qt Version: 5.15.3
Frameworks Version: 5.89.0
Operating System: Linux 5.11.0-43-generic x86_64
Windowing System: X11
Distribution: KDE neon User - Plasma 25th Anniversary Edition
DrKonqi: 5.23.4 [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.

The reporter is unsure if this crash is reproducible.

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