Application: marble (2.2.20 (2.3 development version))

Qt Version: 5.11.2
Frameworks Version: 5.49.0
Operating System: Linux 4.16.0-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (buster)

-- Information about the crash:
Marble works normally, but it segfaults if I close it. Maybe it's related to my setup, as I'm running Plasma inside a VM (KVM w/ GNOME Boxes), and though there doesn't seem to be any behavior that helps to trigger this, maybe you can still find the backtrace useful.

The crash can be reproduced every time.

-- Backtrace:
Application: Marble Virtual Globe (marble), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
