Application: gwenview (19.04.2)

Qt Version: 5.12.3
Frameworks Version: 5.58.0
Operating System: Linux 5.1.7-1-default x86_64
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I started gwenview from a konsole window, and it consistently crashed on startup.  There was not much else running on the system, so there certainly was enough memory, the root disk was not full etc.

The crash can be reproduced every time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
