Bug 426566

Application: spectacle (20.11.70)

Qt Version: 5.15.0
Frameworks Version: 5.75.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: Wayland
Distribution: KDE neon Unstable Edition

-- Information about the crash:
- What I was doing when the application crashed:
On Wayland, I configured a few seconds of delay in Spectacle, clicked on "Take a new screenshot" button, unminimized Spectacle, clicked on the button to cancel the delay countdown and closed Spectacle. Less than 5 minutes later, Plasma shown a notification about Spectacle crash.

-- Backtrace:
Application: Spectacle (spectacle), signal: Aborted
Content of s_kcrashErrorMessage: (null)
