Bug 448212

Application: kalarm (3.3.3 (KDE Apps 21.12.0))

Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.12-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
1. Create a display alarm, with the display type set to Notification (not Window), and Sound to Beep. (I'm not sure the sound matters.)
2. When the notification pops up, click Defer.
3. OK the window that pops up. KAlarm immediately crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KAlarm (kalarm), signal: Segmentation fault
