Description Lapineige 2021-08-15 21:25:07 UTC

SUMMARY
Since the last (backports) update, I can't open ARW file in Gwenview anymore.
Other RAW format works (tested CR2 / RW2), the internal Jpeg preview is shown, but not ARW.
It was working right before that.

The only other software I found to have the same kind of error is https://gitlab.gnome.org/YaLTeR/identity.

STEPS TO REPRODUCE
1. Open an .ARW file with Gwenview

OBSERVED RESULT
"File loading failed" error message

EXPECTED RESULT
Internal image Jpeg preview is shown.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 21.04
(available in About System)
KDE Plasma Version: 5.22.4
KDE Frameworks Version: 5.85
Qt Version: 5.15.2

Thumbnails in Gwenview "folder view"/"grid" mode works.

Here is the console log when I try to open one .ARW file:

> gwenview.libtiff: Error MissingRequired "TIFF directory is missing required \"ImageLength\" field"
org.kde.kdegraphics.gwenview.lib: QImageReader::read() using format hint "tif" failed: "Erreur inconnue"
org.kde.kdegraphics.gwenview.lib: A bad Qt image decoder moved the buffer to 242 in a call to canRead()! Rewinding.
org.kde.kdegraphics.gwenview.lib: Image format is actually "tiff" not "tif"
gwenview.libtiff: Error MissingRequired "TIFF directory is missing required \"ImageLength\" field"

gwenview.libtiff: Error MissingRequired "TIFF directory is missing required \"ImageLength\" field"


Any chance that "format error" (?) is related to https://bugs.kde.org/show_bug.cgi?id=439519 ?

For the record, the other software where I encounter this issue, Identity, is based on GStreamer: https://gitlab.gnome.org/YaLTeR/identity/-/issues/16
I don't know if there a common base between Gwenview and GStreamer (library used ?), but just in case, I'm referencing it here.

As said here https://bugs.kde.org/show_bug.cgi?id=441664#c1 :

> This is probably some KDE package vs Gwenview issue (maybe Arch related) as Geeqie/showfoto/photoqt are working perfectly fine.

Same for me.

I guess there is a common library that is buggy ?

I can provide ARW file if someone wants to investigate, for my part I have no clue where to search for the source of that issue…
