SUMMARY
I just started noticing this problem. An hour ago I upgraded from Plasma 5.27.5 to 5.27.6 (and a week ago from applications 23.04.1 to 23.04.2, but I’m not sure which is the cause, because I haven’t used Gwenview extensively in the last week).

OBSERVED RESULT
Gwenview now shows most of the items in the metadata pane twice. There are exceptions, such as the filename, user comment and date of modification. I assume because they come from different data sources.

EXPECTED RESULT
Each item should only be shown once.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0?
Comment 2 Frank Steinmetzger 2025-08-22 20:22:45 UTC
Yes it’s still there, I’m on 25.08.0 in Arch.

I’m trying to reproduce a “broken” image, but can’t remember how. Because the problematic images must’ve been created by a script of mine which wraps around cjxl to generate Jpeg-XL from jpeg. My script originally first called the converter, and then transferred the EXIF data from the jpeg to the jxl file in a dedicated step via exiftool -tagsFromFile. What I didn’t know was that cjxl also does that itself (maybe it didn’t when I first created the script, which is why I built it in in the first place, but my memory is vague on that).

Interestingly, the preview pane in Dolphin shows the values only once for an affected file. The Exiftool output also looks unconspicuous and I even looked at the file with Okteta and did not find any duplicate strings.

I back-converted the broken jxl to jpg (both with djxl and gimp) and this shows fine in Gwenview. The exiftool output of both files is identical with regard to this issue.

I’ll attach an image for you to try. Unfortunately I have to use the full size, because shrinking it “unbreaks” it.
Comment 3 Frank Steinmetzger 2025-08-22 20:24:48 UTC
The image is too big at 7 MB. I’ll send you a mail with it.

Thanks for making the effort to reproduce.
