Description Christophe Marin 2020-02-06 09:00:47 UTC 
Also reproducible with a local git build:

Performing operation on any picture triggers the crash (eg, after pressing "apply" after cropping an image or using the "flip" button)

New crash information added by DrKonqi

gwenview (20.08.2) using Qt 5.15.1

- What I was doing when the application crashed:
The same as reported before. Cropping an image results in crash of Gwenview

- Unusual behavior I noticed:
What was unusual is that I can reproduce this every time except times when Gwenview was opened from Dolphin using some weird theme. For me reproducing was:
1) close all doplhin instances
2) take a screenhost using spectacle and save it
3) open containing folder via spectale interface
4) dolphin will open but looking like old windows instead of regular breeze theme, even requires double click to open files
5) open gwenview and now I am able to crop files without crash

-- Backtrace (Reduced):

Comment 2 Christophe Marin 2021-09-13 09:19:21 UTC 
Still valid on master. The backtrace is different however.

reproduced on different pictures with different operations (crop, rotate...)
