Application: gwenview (19.12.3)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-37-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Changing my desktop background and selected a jpg in Dolphin.  Gwenview attempted to open it but all that appeared were borders surrounding a transparent center (similar to what has been described in other reports)

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
