Summary: Slideshow freezes and stops responding when
encountering JPEG with 0xDEADBEEF marker in EXIF
UserComment field
Classification: Applications
Product: digikam
Version First 9.0.0
Reported In:
Platform: Microsoft Windows
OS: Microsoft Windows

Slideshow crashes when displaying JPEG images with 0xDEADBEEF
marker in EXIF UserComment field (Samsung GT-I9505 smartphone photos).
Steps to reproduce:
1. Create a slideshow containing at least one JPEG with a
0xDEADBEEF marker in the EXIF UserComment field.
2. Start and process the slideshow
3. Wait until the slideshow tries to load the affected image
Observed result:
The slideshow freezes on the image preceding the affected one
and digiKam stops responding entirely.
Expected result:
Slideshow displays all images without crashing
Root cause identified:
Affected JPEGs contain EXIF UserComment field with 0xDEADBEEF
debug marker written by Samsung firmware (I9505XXUENA1).
Removing the description field in digiKAM fixes the crash.
System:
- digiKam 9.0.0 / Qt 6.9.1 / KDE Frameworks 6.17.0
- Windows 11 25H2
- NVIDIA GeForce GPU
