Application: digikam (5.9.0)

Qt Version: 5.11.2
Frameworks Version: 5.52.0
Operating System: Linux 4.15.0-39-generic x86_64
Distribution: KDE neon User Edition 5.14

-- Information about the crash:
- What I was doing when the application crashed:
digikam crashs upon quit, just after click on "Quit" in Files menu.
Therefore, application seems quit with no gui blocked.

- Unusual behavior I noticed: No ?

- Custom settings of the application:
SQLlite database.
Default configuration
French translation.

The crash can be reproduced every time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
