Bug 452962

Application: kalarm (3.4.0 (KDE Apps 22.04.0))

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.17.4-arch1-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I created a new audio alarm, selected a sound file, set a volume and a fade time. When using the try button to test the alarm, clicking the try button again to stop the test crashes KAlarm.

Also the volume slider that is enabled after selecting the "Set Volume" checkbox doesn't has any effect for me, it's always playing at maximum volume. Sometimes the slider doesn't work, sometimes it does. I haven't figured out what's causing it to not work.

The crash can be reproduced every time.

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