Bug ID: 481140
Summary: Gwenview crashes when cropping image
Classification: Applications
Product: gwenview
Version: Other (add details in bug description)
Platform: Neon
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: fi...@tutanota.com
Target Milestone: ---
SUMMARY
Gwenview crashes when I try to crop a PNG image. There seems to be a
relationship between the image height and the minimum x / y of the crop. Divide
the image height by about 13 for the threshold at which Gwenview will crash. So
for images 10 000 pixels in height, Gwenview crashes when the crop box goes
below 754, for 4000px it's 302, 800px it's 61 etc. For images under 600px
height, Gwenview crashes when the crop box goes below 46. Running Gwenview from
Konsole, I get these details when it crashes:
`ASSERT: "!(max < min)" in file
/usr/include/x86_64-linux-gnu/qt6/QtCore/qminmax.h, line 46
Aborted (core dumped)`
STEPS TO REPRODUCE
1. Open an image with Gwenview. I have seen this happen with PNG files.
2. Select "Show Editing Tools -> Crop -> Advanced Settings" to show the Size:
[x] [y] text boxes.
3. Reduce the x or y crop size number to below about a 13th of the image
height.
OBSERVED RESULT
Gwenview freezes, then crashes and closes.
EXPECTED RESULT
Crop
