Bug 437674

Application: spectacle (21.04.1)

Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.6-arch1-1 x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed: I was closing Spectacle with the "x" button.

I don't have debug symbols for Qt, but I did get some debug symbols for the kImageAnnotator lib, which shows it crashing in a destructor. Presumably it's trying to delete something that doesn't exist.

The crash can be reproduced every time.

-- Backtrace:
Application: Spectacle (spectacle), signal: Segmentation fault
