Created attachment 183837 [details]

Report is pretty simple, and an example of a screenshot is attached. If you think this is due to something with the way the package is compiled, please help me figure this out. The build log is available here:

Cannot reproduce on 
Gwenview: 25.08.0
KDE Frameworks: 6.17.0
Fedora 42

So this is probably NixOS related. Do you have access to the newer 25.08 version?

Comment 2 Doron Behar 2025-08-21 09:38:33 UTC

Hey so thanks for the reply and for sorry for my late reply. Indeed Nixpkgs has updated all KDE packages etc. to 25.08.0 here:

https://github.com/NixOS/nixpkgs/commit/ccc31df75e0d5dbac91c20bbd264cc8610d1fc59

And with it, I still don't see an SVG thumbnail. Maybe it is relevant, I'm seeing this in the terminal when opening an SVG file:

```
org.kde.kdegraphics.gwenview.lib: Unresolved raw mime type  "image/x-samsung-srw"
```

Thanks for checking, I had the small hope that it got fixed right away..

Probably not, this is a pretty standard debuginfo.

The problem is that this seems to be a NixOS-exclusive issue. Most people here don't run it, so we cannot reproduce the bug, which is important for testing and fixing it.
As NixOS is a rather arcane distro (no offense), could it be that this is a bug from downstream, i.e. NixOS doing something wrong?

I don't wanna shift the blame to NixOS, but am unsure on how to proceed here. Probably we would just leave this report open as REPORTED or NEEDSINFO WORKSFORME/DOWNSTREAM and wait, if it disappears by itself or others chime in with similar problems.

What do you think?

Comment 4 Doron Behar 2025-08-21 16:17:00 UTC

OK I see. I might ask for help from the NixOS forums. In anycase, is there no way I can debug this? I won't mind recompiling this package with debug info, or add debug prints or whatever - I just wish to get a bit of help for this.

I am not a Gwenview dev, so I cannot really help you there.
