Application: spectacle (19.12.3)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-47-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Trying to take a screenshot of the active window.

- Custom settings of the application:
It was set to _On click_ and wasn't set to show the mouse cursor.

I got a message about it not being able to create the temporary file, but I don't remember the exact wording and I didn't get a screenshot.

The crash can be reproduced every time.

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